Inverse Trig Functions Calculator

1. Select Function: Arcsin (sin⁻¹), Arccos (cos⁻¹), or Arctan (tan⁻¹).
2. Input Value: Enter the ratio (must be between -1 and 1 for sin/cos).
3. Result: See the angle in Degrees and Radians.

The Inverse Trig Functions Calculator computes the angle when the ratio of sides is known. It calculates Arcsin, Arccos, and Arctan.

This is commonly used in construction to find the angle of elevation or depression.
