cosine. Example: Angle in degrees: 30 degrees gives 0.866025403784 number. Angles supplied in degrees; tangent restricted to −80..80 to avoid poles. Sine/cosine accept −360..360. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation.
Angles supplied in degrees; tangent restricted to −80..80 to avoid poles. Sine/cosine accept −360..360. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation. Derivation: Convert degrees to radians before standard real trigonometric evaluation.
Accepted inputs: Angle in degrees: -360 to 360 degrees.
How the calculation works
