Inverses of sin, cos and tan

Want to work backwards from trig values to angles? This playsheet introduces the inverses of sine, cosine, and tangent—also written as sin⁻¹, cos⁻¹, and tan⁻¹.

You’ll learn how to use these functions to find unknown angles in right triangles using your calculator.

Each problem helps you connect trig ratios to angle measures in both degrees and radians.
