]]>The dot product is a scalar representation of two vectors used to calculate the angle between them in any dimensional space. Contrarily, the area or volume of a parallelogram formed by ** a**,

In the article below, we would go through the importance of both dot and cross product of two vectors in Math.

** Cross Product**

The cross product a b is defined as a vector c that is perpendicular (orthogonal) to both a and b, with a magnitude equal to the area of the parallelogram that the vectors span and a direction provided by the right-hand rule. The size of the parallelogram with two sides A and B is the magnitude of the cross product.

Contrary to the dot product, which is a measure of how similar two vectors are, cross product is a type of "difference" metric between two vectors. With a cross product, the bigger the magnitude of cross product, the more perpendicular the two vectors are.

The cross product is used to find out the angle between two vectors, find a vector normal to a plane, calculate the moment of a force about a point, and calculate the moment of a force about a line, among other things. However, some other uses and significances of cross product are provided below.

**Importance of Cross Product**

The cross product, often known as the vector product or directed area product to underline its geometric importance, is a binary operation on two vectors in three-dimensional space indicated by the symbol ** a** x

The dot product as we know determines how much two vectors point in the same direction, whereas the cross product determines how much they point in opposite directions. To get a vector that is perpendicular to the plane covered by two vectors, the cross product is used.

Cross product is incredibly significant in many kinds of sciences especially mathematics, engineering, and physics since it is a vector operation. The main significance of cross products in math lies in finding the direction of two vectors in opposite directions. but sometimes cross product can be difficult because of various directions and complex questions. Here I advise to use cross product calculator as it is globally accepted for its correct answers and easy solutions. Same as integral calculator for calculus

**Dot Product**

The value that is utilized to represent the angular relationship between two vectors is the dot product of two vectors. Now in this section we will see what a dot product is, its mathematical importance and how to compute this product.

A dot product is a scalar value formed by combining two vectors while having same number of components. The dot product of two vectors A and B, each with n components, is computed as:

A . B = A1B1 +... + AnBn

Therefore, the total of the products of each component of the two vectors forms the dot product. If A and B were 3D vectors, for example then

** A . B** = A.x * B.x + A.y * B.y + A.z * B.z

**Importance Dot Product**

The dot product being a basic method for combining two vectors also informs us how much two vectors are pointing in the same direction intuitively. The dot product also called the scalar product is really significant for determining if two vectors are orthogonal.

However, when the angle between two vectors is 90 degrees, they are said to be orthogonal. The dot product, on the other hand, can only be zero if the angle between the two vectors is 90 degrees, or if one or both vectors are the zero vector.

Thus, if and only if two non-zero vectors are orthogonal, their dot product is zero. Moreover, the angle between 27-dimensional vectors may be calculated using dot product. Thus the dot product calculates the angle between any two vectors. It's one of the most significant vector connections.

The dot product calculates the angle between two and three-dimensional vectors as well. Therefore, we can say that the angle formed by two vectors of any dimension is given by the dot product. It's a difficult notion to grasp, but it's correct.

Chemistry is a subject of various reactions taking place and these reactions are represented using the chemical equations. The chemical equation balancer plays a huge contribution in chemical reactions as it is the standard way of representing a chemical reaction.

In a chemical equation the reactants and products involved in a chemical reaction are represented symbolically. The reactants or the reacting substances are represented on the left hand side of the equation while the products or resultant entities are presented on the equation's right hand side.

Both the reacting and producing substances are separated in the equation by an arrow. However, the direction of the arrow represents whether the reaction is reversible or irreversible.

In chemical equations the equilibrium or balance on both hand sides is an imperative factor. A chemical equation must be balanced accurately in order to maintain an equilibrium among reactants and products. Moreover, the law of conservation of mass, which states that mass can neither be created nor destroyed during a chemical reaction, must need to be fulfilled.

In other words, the foundation for a balanced chemical equation is the law of conservation of mass. And when implementing this law, the number of each element or compounds, atoms and molecules in the equation should be kept equal on both hands.

Thus a balanced chemical equation should maintain an equilibrium among atoms and molecules of reactants and products. The number of atoms in a chemical equation is represented by the subscripts before the element’s symbol. While the number of molecules involved in the reactions are represented by the coefficient written just after the chemical formula.

However, when writing chemical reactions in equation form you have to balance them by your own as they don’t come already balanced. So before using any equation in your required chemical reaction first balance it accordingly ten deal with it.

The law of conservation of mass which governs the equation balancing is that we must present as many atoms and molecules with the products as much we have with the reactants. Thus the total mass of the products must be equal to the total mass of the reactants. Balancing

The half-life is the phenomenon that is a part of physics, chemistry as well as the biological field. As the name implies the half-life is something related to the half-life or half existence of matter or substance.

However, we would define it as the time required by the half of a reactant or chemical substance to be consumed from the initial quantity. This means the half-life of any substance is the time taken by it to be converted into half quantity from the preliminary quantity.

The thing to be considered here is that the half-life of any substance has nothing to do with its physical quantity. That means there should be no change in the mass of the substance, however, the 50 percent decay of the substance's atom will occur. Online half life calculator with steps define half-life process very clearly and calculate the half-life accurately.

For instance, if a radioactive substance has a half-life of 70 years that means after 70 years half of its atoms would undergo chemical decay with no change in mass. The half-life of any element could be as much as billions of years to as minimum as a few seconds. However, it is expressed in seconds and denoted by the expression t1/2.

This significant property of matter decaying is highly implemented in nuclear physics, to calculate the timing required to undergo radioactive decay by unstable atoms and for how long the stable atoms could survive.

As mentioned above, in order to calculate the half-life of any substance the expression t1/2 expression is used but along with this expression following aspects must need to be known as well:

Rate constant which is expressed as “k”

Order of the reaction

Initial concentration which is expressed as [Ao]

How to cope up with the horror of geometric and algebraic questions? The solution is very simple. You do not need to panic. And read these super easy steps to digest these questions.

**Do not select studying Algebra firstly**

When you sit to study, start with your favorite subject. But never start with algebra or geometry. Because when you have started with the subjects you do not like, You will get frustrated and leave studying. And could neither study Algebra nor Biology. So start solving algebraic operations after studying your favorite one.

**Get out of the false Geometric measurements**

Geometric questions are complex and never understandable. And sometimes they seem completely illogical. But they are not! When you have read a question statement about drawing a triangle of .... measurements. First, analyze the statement completely because sometimes only a minor mistake ruins your question as well as mood.

So make sure to analyze the proper unit of measurement. Whether it's in meters or centimeters then start solving questions.

**Practice the geometry questions daily**

"Practice makes a man perfect" make your daily habit to solve at least one or two questions daily. Instead of carrying a burden of study on exam day, Be more organized in solving a question daily.

**Never attempt to "cram" the Algebra solution**

It is reported by many students that they prefer to learn the solution by heart instead of solving it logically. According to them, it is a short cut method to remember them. But it is a completely useless practice. Never attempt it especially in final exams.

Because once you get stuck in a single step, You will forget everything and you will not be able to solve the question logically. So only follow the path of hard work and concept.

Understand the mathematical terms and questions than write them in a notebook. Results will be disastrous if you follow cramming in Algebra.

**Remember the basic terms**

Before studying any subject it is important to read their basic points. These core points build the structure of any subject. To learn geometry you have to be familiar with the basic terms like:

**What is Midpoint**

Midpoint is the central point in the line segment. Midpoint has an equal distance from the two endings points of the line segment. Its definition is simple but it is difficult to calculate the midpoint. You have to memorize the formulas for calculating it.

The formula for calculating the midpoint is:

**=(x1+x2/2,y1+y2/2)**

But the point of relaxation is you can solve these questions without remembering the formula! And only using a midpoint calculator. It is the predesigned online calculator that is specific to solve such questions.

**What is Arc length**

Arc length is the length of the arc of a portion of a circle. And this arc is part of the total circumference of a circle. Similarly, you have to follow a typical methodology for solving it. But you can save yourself from a tough situation by using an Arc length calculator.

**What is the Pythagorean theorem**

Pythagorean theorem is a fundamental theorem or formula in mathematics. It involves the square of the three sides of a triangle including hypotenuse, Base, and perpendicular. Although it is not that difficult and complex the problem arises when you are supposed to complete the bundles of math homework including these questions. At that time, You can take help from the Pythagoras theorem calculator for solving these questions.

But make sure to know about the statistics and the relevant data for the other companies. Because if you take only the data of one company and not try to compare it with the other companies you will not get accurate results. If you want to fetch correct data then you need to compare the data of certain companies to make an accurate decision. This will help you make a net profit at a peak level.

Have you seen the **Impact of ROI and ROA on finance? **If you are a businessman this will help you if you have an idea about these two terms, ROI and ROA. Because these are extensive terms and used for many purposes at the local level and at the high level to maintain the business, its profit and losses.

We cannot completely eliminate the chances of error, but we can devise ways to reduce these errors. For example, in some chemistry experiments, we calculate the actual yield of the chemical reactions and then compare it with the “theoretical yield”.

When we know the percentage error, we can try and standardize our experiment, i.e. careful adding of the solvents, avoiding spillage etc. In this article, we will emphasize on ways to find out the percentage of error in our routine measurements.

Now, let’s get started, here are a few of the best possible methods of calculating percent yield:

One of the easiest to use method is to get help from an online tool. You may find a bunch of online tools that are smart enough to compute any problem you feed it with.

One such tool is a “percent error calculator”, this easy to use gizmo is well equipped in finding the error percentage, given the true and observed value. All you need to do is enter the required values in the given fields and press calculate.

No need to work out with formulas and calculations, here just leave the math work on this online tool and relax. The advanced digital technology has really made our lives much easier.

Now, let’s get to basics and calculate the percentage of error in our findings, using the formula. Before moving towards formula, know some of the terms. **True value** means the expected value that should have been acquired at the end of the results, if our findings were to be error free.

On the other hand, the **observed value is** the value obtained having some errors, most often human error.

Percent error = True value – observed value/ True value * 100

Assume, you are conducting a physics experiment, regarding the speed of sound.

Here, True value of speed of sound is 343 meter per second in air at 20◦c.

The value observed after the experiment was 332 m/s.

Percent error = 343 – 332 / 343 * 100 = 11/343* 100 = 3.2%

You can take help from excel, just enter the data, true and observed values in separate cells. Then, using the same formula mentioned above, you can easily calculate the percent error with speed and precision without doing any calculation on your own.
