Chapter 7: Q. 22 (page 450)

Find the exact value of each expression.

sin-1(-32)

Short Answer

Expert verified

The exact value is -蟺3.

Step by step solution

01

Step 1. Given information

We have been given an expression sin-1(-32).

We have to find its exact value.

02

Step 2. Find the value using unit circle.

We can write:

sin-1(-32)=x;-蟺2鈮�x鈮�蟺2

So,

role="math" localid="1647670115500" sinx=-32

The range of function is [-蟺2,蟺2].

Using the unit circle,

sin-1(-32)=-蟺3
