y=1\3logtan(cosx+sinx\cosx-sinx)

prove(sinx/cosx+1)+(cosx-1/sinx)=0 Please help asap!!!!! PLEASE

secx/sinx-sinx/cosx=cotx

sinx/1-cosx+1-cosx/sinx=2cscx

Prove 1-cosx+sinx / 1+cosx+sinx =tan x/2

Prove that 1+cosx+sinx/1-cosx+sinx=cotx

cosx+sinx/cosx-sinx = sec2x+tan2x

Diffrentiate In(cosx+sinx/cosx-sinx)

Differentiate In(cosx+sinx/cosx-sinx)
