Question

what are trigonometry complex equations ​

Answer 1

Answer:

All complex trigonometric functions are periodic functions with the same periods as trigonometric function for real variables. Cos(z) is an even function, Sin(z) is an odd function as trigonometric functions for real variables. These identities are based on the Pythagorean theorem.
