Question

prove this identity​

Answer 1

LHS: (1/ cos ^ theta)/( sin ^ theta / cos ^ theta)+(1/sin ^ theta)/( cos ^ theta / sin ^ theta)

(1/ sin ^ theta)+(1/ cos ^ theta)

(sin ^ theta + cos ^ theta)/ sin ^ theta . cos ^ theta

1/ sin ^ theta . cos ^ theta

cosec ^ theta . sec^ theta .

LHS = RHS. ( proved)
