Answer 2

1. Use the unit circle to find the inverse function value in degrees. tan^-1 √3

2. Use a calculator to find the value of the inverse function in radians
sin^-1 (0.65)
0.71
-3.85
0.86
-0.61

Answer 3

1. The unit circle shows that tan 60° = √3. Therefore, tan^-1 √3 = 60°.

2. Using a calculator, sin^-1 (0.65) ≈ 0.71 radians.
