Provide all trigonometric functions #227
Description
Starting with #225, it's probably a good long term goal to implement all hyperbolic and non-hyperbolic trigonometric functions:
-
cosh -
arccos -
arccosh -
sinh -
arcsin -
arcsinh -
tan -
tanh(implemented in Implement tanh, fixes #225 #226) -
arctan -
arctanh
Reusing the macro used in #226 to implement tanh, the other functions should be quickly implementable.
