@skeeter: Yes , but then I'm left w/ (cosxcotx(secx-tanx) + sinx(sexc + tanx). I tried putting all of tht in terms of sin & cos & eventually reached the point [(cos^2x(cosx-sinx)+ sin^2x(1+sinx)]/(sinxcosx)]

Yes, when you double post, and your duplicate post gets deleted, then the help in the duplicate gets deleted as well, wasting time and effort of those trying to help.

I don't think changing every term to sines and cosines will do much good from this point ... do you know what it is supposed to simplify to? - Nov 13th 2012, 05:06 PMhunnyelleRe: Simplify [(cosxcotx)/(secx+tanx)] + (sinx)/(sex-tanx)]
The answer is cotx -cosx + tanx +sinxtanx, & I've figured out how to reach that answer!
