    what did you do to the right? What is the assignment, are you proving one side equal to other, or solving equation?

    \[\frac{ 1-\cos \theta }{\sin \theta } =\frac {\sin \theta } {1+\cos \theta }\]

    i can work on either side but once i start working on one side im limited to that side.

    sin^2 x = 1- cos^2 x = (1+cosx)(1-cosx)

    multiply the top and bottom by cos(theta) .right, then use identities to simplify.

    It requires algebraic manipulation. Continuing from Algebraic work above|dw:1352775535108:dw|

    Above is left hand side only, continuing from Algebraic start. Working on lefthand side only.
