A simple solver for trigonometric equations.

Project description

triangles is a package for easily solving simple trigonometric equations. It contains only a single function which takes the name of the sought side length, an angle in degrees and a side length as seen from that angle. It returns the length of the sought side.

The sought side must be a member of ["adjacent", "opposite", "hypotenuse"].

The solve function returns either the the value the solved equation would return, or the equation required to solve the problem given the provided data or, if the solve flag is set to False.

Usage:

>>> from triangles import solve
>>> solve("adjacent", 60, hypotenuse=1000)
500.0000000000001
>>> solve("adjacent", 60, hypotenuse=1000, solve=False)
'hypotenuse * math.cos(angle)'
>>> solve("opposite", 53, adjacent=7)
9.289313751342869
>>> solve("opposite", 53, adjacent=7, solve=False)
'adjacent * math.tan(angle)'
>>> solve("hypotenuse", 68, opposite=70)
75.49743198743084
>>> solve("hypotenuse", 68, opposite=70, solve=False)
'opposite / math.sin(angle)'
