Question

hey mate please prove this identities​

Answer 1

Your answer is in the attachment.

• Note : cot A = 1/tan A and 1/cos A = sec A and 1/sin A = cosec A.

• Note : I shifted 2 to L.H.S for better results.

Hope it helps!

Answer 2

Hello,

Here we go,

By taking the LHS side

tan²A + cot²A

sec²A - 1 + cosec²A - 1

sec²A + cosec ²A - 2

1/cos²A + 1/sin²A - 2

sin²A + cos²A/cos²Asin²A - 2

1/cos²Asin²A - 2

sec²Acosec²A - 2 = RHS

Hence proved ,

I have used the following identities to solve this problem,

tan²A = sec²A - 1

Cot²A = cosec²A - 1

Cos²A + sin²A = 1

I hope my answer will help you to solve your problem.
