Prove that ((cos A+cos B)/(sinA-sinB))^(...

Prove that `((cos A+cos B)/(sinA-sinB))^(n)+((sinA+sinB)/(cos A-cosB))^(n)`
`=2cot^(n)""(A-B)/(2)` or 0, accordingly as n is even or odd.

A

Statement-1 is True, Statement-2 is true, Statement-2 is a correct explanation for Statement -1.

B

Statement-1 is True, Statement-2 is True, Statement-2 is not a correct explanation for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
A
Clearly, both the statements are true and statement-2 is a correct explanation for statement-1.
