Question

(cotA-cosecA)^=1-cosA/1+cosA​

Answer 1

Answer:

this answer requires a second degree in on the lhs

Explanation:

yeah , so when you square the L H S, you get

cot^2 A + cosec^2 A - 2 cotA.cosecA

since, cotA= cos A / sinA and cosec A = 1 / sinA

so, simplifying it further will lead to:

=> .      cos^2 A + 1 / sin^2 A  -  2cosA / sin ^2 A

=>         cos^2 A + 1 - 2cosA / sin^2 A

=>        (1 - cosA)^2 / 1 - cos ^2 A

ig the you need to verify the question
