cos(PythonObject) -- cosine of a python object

Function: cos
Usage:

cos x
Inputs:
- x, a python object,
Outputs:
- a python object,

Description

This calls Python's built-in math.cos function, which computes the cosine of x.

i1 : cos toPython 0

o1 = 1.0

o1 : PythonObject of class float

i2 : cos toPython (pi / 2)

o2 = 6.123233995736766e-17

o2 : PythonObject of class float
