Answer 1

Given :-

secθ + tanθ = p

To Find :-

secθ - tanθ

Answer :-

1 / p

Solution :-

We know ,

sec² θ - tan² θ = 1

=> ( secθ )² - ( tanθ )² = 1

=> ( secθ + tanθ ) ( secθ - tanθ ) = 1

[ • Using Identity , a² - b² = ( a + b ) ( a - b ) ]

=> p × ( secθ - tanθ ) = 1

=> ( secθ - tanθ ) = 1 / p [ • Required Answer ]
