In Python I want to move an object away from a second object by calculating the length of the hypotenuse, adding to its length and then calculatin the x and y co-ordinates of the new position. To do this I’m using the Python math module.

From my school days I remember ‘soh car toa’ where a is the adjacent side of the angle, h is the hypotenuse and o is the opposite side to the angle.

As a test my code is:

import math

a = 30
o = 40
h = math.sqrt(o*o+a*a)                  #  should = 50
ta = math.tan(o/a) * 180 / math.pi      #  toa
ca = math.cos(a/h) * 180 / math.pi      #  cah
sa = math.sin(o/h) * 180 / math.pi      #  soh
print(" : hypotenuse = ",h,"n : tan angle = ",int(ta),"n : cos angle = ",int(ca),"n : sine angle = ",int(sa))

I would have expected the answers to all come back with the same angle, but they don’t. These are the answers I get:

 : hypotenuse =  50.0 
 : tan angle =  236 
 : cos angle =  47 
 : sine angle =  41

Why are the answers so different and/or what am I doing wrong?
