- How can we use inverse trigonometric functions to determine missing angles in right triangles?
- What situations require us to use technology to evaluate inverse trigonometric functions?
arcsin(1/3)in Desmos, we find that \(\alpha \approx 0.3398\) radians. Note well: whatever device we use, we need to be careful to use degree or radian mode as dictated by the problem we are solving. We will always work in radians unless stated otherwise.
