cot(x) / csc^2x + cscxcotx-1 = sinx/1+cosx

Working on left-hand side

cot(x) / **csc^2x** + cscxcotx-1

cot(x) / **1+cot^2x** +cscxcotx-1

**cancel out constants**

cot(x) / **cot^2x+cscxcotx**

cot(x) / cotx(cotx+csx)

cot(x) / **cotx**(cotx+csx)

**cancel out cotx**

1 / (cotx+csx) = sin(x)/(1+cos(x))

And im stuck on what to do here next.
