# If , prove that =

Given:

Now, squaring both the sides, we get

p2 = q2 tan2θ …(1)

Now, solving LHS

Putting the value of p2 in the above equation, we get

[ 1+ tan2 θ = sec2 θ]

(from Eq. (1))

[(a + b) (a – b) = (a2 – b2)]

Now, we solve the RHS

[ 1+ tan2 θ = sec2 θ]

LHS = RHS

Hence Proved
