prove that tanalpha / 1 + tan2alpha + cotalpha / 1+ cot2alpha = sec alpha cosec alpha + 2 sin alpha cos alpha

Dear Student,

Taking A in place of alphaα and solving

The correct R.H.S is secA cosecA- 2sinA cosA.

Your question appears to be typed wrongly, the correct answer is secA cosecA- 2sinA cosA.

Hope this information will clear your doubts about topic.

If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible.
