Description

The function cos() takes x as an argument and returns y such that y_i = cos(x_i). The x_i are in radians. For complex arguments, the complex cosine is returned.

The function cosh() takes x as an argument and returns hyperbolic cosines y such that yi = cosh(xi). For complex arguments, the complex hyperbolic cosine is returned.
