just olya [345]

The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β

<h3>What are Trigonometric Ratios ?</h3>

In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.

The trigonometric expression given in the question is

(1+cosβ)(1−cosβ)sinβ

(a+b)(a-b) = a² - b²

( 1 - cos²β)sinβ

By the trigonometric Identity

1-cos²β = sin² β

 sin² β x sin β

sin³β

Therefore Option B is the correct answer.

Answer:

23

Step-by-step explanation:

In this question, we want to evaluate the expression "9z-4" for z=3.

This means, we want to calculate the result when we substitute the z in this expression for 3.

So we have: 9(3)-4, which is equal to 23.

Let me know if this helps!
