Chapter 7: Q. 1 (page 503)

In Problems 1– 8, find the exact value of each expression. Do not use a calculator
$\sin^{- 1} 1$

Short Answer

Expert verified

The exact value is $\frac{π}{2}$ .

Step by step solution

Step 1. Definition

The inverse sine function $y = \sin^{- 1} x$ means that $x = \sin y$ where $- 1 \leq x \leq 1$ and $- \frac{π}{2} \leq y \leq \frac{π}{2}$ .

Step 2. Find the exact value

Let $θ = \sin^{- 1} 1$ , so using the definition of inverse sine function it can be written as $1 = \sin θ$ where $- \frac{π}{2} \leq θ \leq \frac{π}{2}$ .

In this interval the angle for which the sine value is $1$ is $\frac{π}{2}$ .

So the value of $\sin^{- 1} 1$ is $\frac{π}{2}$ .
