Homework Statement
Let W be the wrapping function and suppose f is the real function defined by:
f(theta) = d(W(0), W(pi/2 + theta)) / d(W(0), W(pi/2 - theta))
-Find domain f
-Determine whether f is even, odd, or neither
-Find the zeros of f
-Compute f(theta) in terms of cosine theta and sine theta and simplify the result until it is radical free.
"d" in the equation is the distance.

The Attempt at a Solution
Could someone help me with solving this problem? I'm aware that I should be doing this myself, but I do not understand it at all and my teacher is not good with explaining things. He doesn't tell us where we can find it in the book, so the book is of no help.
