Formula:

The Tangent Tetra Angle Identity allows you to express the tangent of the sum of four angles (A, B, C, D) in terms of the individual tangents. The general formula is:

tan(A + B + C + D) = (S1 - S3) / (1 - S2 + S4)

Where:

  • S1 = tan A + tan B + tan C + tan D
  • S2 = tan A tan B + tan A tan C + tan A tan D + tan B tan C + tan B tan D + tan C tan D
  • S3 = tan A tan B tan C + tan A tan B tan D + tan A tan C tan D + tan B tan C tan D
  • S4 = tan A tan B tan C tan D

Angles A, B, C, and D can be entered in degrees or radians.
