What is the formula of Sin³x?

Solution:

We can find the value by using the trigonometric identity of sin³x

As per trigonometric identity, we have

sin 3x = 3sin x - 4sin³ x

On transposing terms,

4 sin³ x = 3sinx - sin 3x

Divide both sides of the equation 4 sin³ x = 3sinx - sin 3x by 4,

sin³x = (3sinx - sin 3x)/4

Hence the formula for sin³ x is (3 sinx - sin 3x) /4.

What is the formula of Sin³x?

Summary:

The formula of Sin³x is (3 sinx - sin3x)/4
