In this code,
===========start
import math
import numpy as np
from numpy import matrix
def sinD(D): # given in degrees, convert to radians
return sin(radians(D))
def cosD(D):
return cos(radians(D)) <<--------------
def acosD(D):
acos(radians(D))
return=====end
the << line produces, "NameError: global name 'cos' is not defined", but
the sin() above it does not? They are both built-in functions.
