Question

Prove the following fundamental identities

1.) 1 + sin X/cos X = cos X/1 - sin X
2.) sin X/sin X - cos X = tan X/tan X - 1
3.) 1 - sin X/cos X =  1/sec X + tan X
4.) sec^2 X + 2 tan X/1 + tan X = 1 + tan X
5.) sec^2 theta /sec^2 theta - 1 = csc^2 theta
6.) sin theta - cos theta/tan theta csc theta - sec theta cot theta = sin theta cos theta
