sine in python

[Astan Chee]

Hi,
I have a math function that looks like this
sin (Theta) = 5/6
How do I find Theta (in degrees) in python? I am aware of the math.sin
function, but is there a reverse? maybe a sine table in python?
Thanks
Astan

import math
If you now do
dir(math)
you'll see that the module has the functions 'asin' and 'degrees' that
find the inverse sine of a number, and convert radians to degrees,
respectively

Better yet, do

help(math)

which will display the docstrings.

import math
theta = math.asin(5/6) * 180/math.pi

Careful there, bud. 5/6 might not give you the value you're expecting
it to, depending on the version of Python you're using. If you're on
Python 2.x, you'll want to use "from __future__ import division", or
to specify 5 and 6 as floats, i.e., 5.0/6.0.

(And people claim 5/6 == 0 is the "obvious" result....)
