Question

help me and solve this problem

Answer 1

Answer:

Step-by-step explanation:

LHS = (cosec A - sin A)(sec A - cos A)sec^2 A

=(1/sin A - sin A)(1/cos A - cos A)*(1/cos^2 A)

= (1 - sin^2 A)(1 - cos^2 A)/(sin A cos A cos^2 A)

= cos^2 A*sin^2 A/(sin A cos A cos^2 A)

= sin A/cos A

= tan A = RHS
