I'm so glad the members of SF know calculus better than I do lol.
Here is the function to derive: y = ( (1+sin x) / (1-cos x) )^2
This is what I get, but I cannot figure out how to simplify it (hopefully my calculus is correct)
2*( (1+sin x)/(1-cos x) ) * [(cos x)(1-cos x) - {(sin x)(1+sin x)} / (1-cos x)^2 ]
For clarification, in the big trig term, (cos x)(1-cos x) - {(sin x)(1+sin x)} is all over (1-cos x)^2. (If anyone needs this to be clarified, I'll scan a...
