## What do You Mean by Sin Squared X Formula?

Trigonometry is an interesting domain of higher mathematics that students love to study and solve problems. The ratio of the sides of a right-angled triangle expressed in the form of trigonometric ratios and their relation with the angles is quite fascinating to learn. For this, you will have to study the different trigonometric ratios and their identities. These identities will explain what the Sin squared x formula stands for. In this section, you will find out what this expression represents and how it can be used.

### What do You Mean by the Formula of Sin Square X?

Trigonometry is the fundamental branch of higher mathematics that is concerned about the ratios of the sides of the triangles and their representation in the form of symbols such as sine, cosine, secant, cosecant, tangent, and cotangent. These symbols represent a particular ratio of the sides of a right-angled triangle. One such trigonometric ratio is Sine or Sin. An angle is written after it to complete the representation of a particular value of a ratio of two sides. When it is squared, the Sine becomes:

Sin X = perpendicular/hypotenuse = p/h

Sin^{2}X = (p/h)^{2}

Hence, the formula of Sin square X is represented in this way. When this square is doubled then the representation becomes a little different.

Sin^{2}X = (p/h)^{2}

When doubled, 2 Sin^{2}X = 2(p/h)^{2}

As you can see, 2 is multiplied simply with the square of this ratio to get a value. Here, the value of X can be anything. A change in the value of X will also change the value of Sin X.

Let us consider another example here. If the angle is doubled then it will become 2X. What will happen to the Sin squared 2X formula? Let us check.

If the angle is 2X then the ratio will become Sin 2X. When it is squared, the result will be different and represented in the following way.

(Sin 2X)^{2} = Sin^{2}2X

Check and understand the difference between the square of the sine of an angle and the same of the angle doubled. Learn how to represent these expressions properly so that you can avoid confusion while solving trigonometric problems in the exercise and in the exams.

### Learn the Difference Between the Sin Squared X Formula and Others

It is of utmost importance to learn how to represent the Sin squared X formula when you are studying the trigonometric ratios and the relevant identities. When you will proceed to the next level in an advanced class, these representations will be required. Understand the meaning of every expression first and then learn the differences.

### Conclusion

Follow the explanation given above and find out what the formula of Sin square x means. Then proceed to the other explanations as well to grab hold of the concepts. These concepts will be required in mathematics and science subjects in the future.
