Question

What is the value of sin^-1(0)
a= -1
b= 0
c = 1
d = pi

Answer 1

B: 0

Explanation:

At the unit circle, we can see that sin(x) = 0 for x = 0 and for x = pi

This gives us directly that sin^-1(0) = 0 or x = pi

However, the function sin^-1(x) is only defined for -pi/2 \leq 0 \geq pi/2, since otherwise it is very unclear which answer is the right one.

By this definition, we directly see that the only right aswer is 0
