Confusing math question

Answer 1

Find the exact value of s in the given circular function value. Do not use a calculator.

[0, pi/2]; sin s = sqrt3/ 2

I will be offline for an hour because my grandfather needs me. Can you please show me how to do this? Thank you.

Answer 2

Use the unit cirycle. The x-coordinates give cosines and the y-coordinates give sines. The part in brackets tells you that you're looking for angles between 0 and π/2 inclusive. That's the first quadrant. So you're looking for the angle in radians that has a y-coordinate of \(\frac{ \sqrt{3} }{ 2 }\).
