How do I simplify this problem (so that the Right Side is equal to the Left Side)?
cosx - (cosx)/(1-tanx) = (sinx cosx)/ (sinx - cosx)

Without telling you the entire solution, I will give you some hints. First, change everything into sines and cosines, so the tangent must equal sine/cosine. From there, you can multiply out and see the equality.
I am going to post a scan of the work that I did...i think that I might be on the right track, but messed up somewhere...it will just take me a minute to upload...
Please ignore 25 continued...underneath it....it is another problem
You are right so far except your denominator has disappeared.
It must be:
The numerator can be simplified to
Then as previously stated change in the denominator to
Now I have got:
-sinx/ 1-(sinx/cosx) What do I do now?
