can someone solve this ?
1+tgx / 1-tgx
final result should be

Is tgx something like tan x?
If so, then I'd multiply top and bottom by cos x.
That gives (cos + sin)/(cos - sin)
Multiply top and bottom by (cos - sin) gives the denominator you want, but doesn't seem to give the numerator you want. Hmm ...
