Question 611261: Find the exact solution of the equation
sin^-1 x = Pi/2
Trying to find what x is in this equation - it is sin to negative 1 power
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
sin^-1 (x) = Pi/2
----
Your problem says "The angle whose sin is x is pi/2"
The angle is pi/2.
Since the sin(pi/2) is 1, x must be 1.
-----
OR
sin(sin^-1(x)) = sin(pi/2)
---
x = 1
