title: Trigonometry in Python
body: <p>I made this calculator to try and calculate trigonometry in python. I've only just started learning how to use this program and I haven't been able to find anything so far that makes sense to me. The problem with this is that I keep getting different answers to those that come up on my scientific calculator.</p>
