GIVEN ;-
⇒ secθ+tanθ = p
TO FIND ;-
⇒ Find the value of secθ-tanθ
SOL ;-
⇒ This sum can be solved through an identity, so -
⇒ Remember the identity - sec 2 A – tan 2 A = 1
----------------------------------------------------------------------------------------
THEREFORE USING THIS IDENTITY , WE CAN SOLVE THIS SUM -
⇒ ( sec A + tan A ) ( sec A – tan A ) = 1
⇒ ( sec A – tan A ) × p = 1
⇒( sec A – tan A ) = 1/p
--------------------------------------------------------------------------------------
⇒ secθ+tanθ = p

Q)secθ+tanθ=p
Multiply secθ-tanθ on both side we get
(Secθ+tanθ)(secθ-tanθ)=p(secθ-tanθ)
Sec^2θ-tqn^2=p(secθ-tanθ)
1=p(secθ-tanθ)
Secθ-tanθ=1/p
