Question

Find the value of sin-1 (tan pi/4 )?
1) a 0
2) pi
3) 2
4) pi/2

Answer 1

The value of sin-1 (tan pi/4 ) is pi/2.

Step-by-step explanation:

To find the value of sin-1(tan(pi/4)), we can use the relationship between sine and tangent. Since tan(pi/4) = 1, we want to find the angle whose sine is 1. The angle that satisfies this condition is pi/2. Therefore, the value of sin-1(tan(pi/4)) is pi/2.
