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

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
