Question

Cscx=cscx+secx/1+tanx

Answer 1

`\csc \left(x\right)=(\csc \left(x\right)+\sec \left(x\right))/(1+\tan \left(x\right))`

`=(1)/(\sin \left(x\right))` (expressed with sine and cosine)

`(1)/(\sin \left(x\right))=\csc \left(x\right)`

`=\csc \left(x\right)`

Therefore, the identity has been proven true.
