Question

What is the value of arcsin (-0.18)? Use a calculator to determine the answer.

Answer 1

the answer for the problem is A.

Answer 2

A) -0.18 rad

Explanation:

arcsin(x) = a means that sin(a) = x

For example

arcsin(1) = pi/2.

It means that pi/2 is the value for which the sin is equals to 1.

arcsin(-0.18)

This is the value of x for which sin(x) = -0.18. This happens for x = -0.18 rad.

So the correct answer is:

A) -0.18 rad
