Answer» As 1=sec^2-tan^2LHS sec+tan - (sec^2 - tan^ 2)/tan -sec + 1 take common sec + tan (1-sec + tan)/tan-sec+1 sec + tan 1/cos + sin/cos 1+sin/cos multiply numerator and denominator by 1-sin we get 1-sin^2/cos-cos sin take cos common from denominator and 1-sin^2 is cos^2 cos^2/cos(1-sin) cos/1-sin = RHS

Answer»

As 1=sec^2-tan^2LHS sec+tan - (sec^2 - tan^ 2)/tan -sec + 1

take common sec + tan (1-sec + tan)/tan-sec+1

sec + tan

1/cos + sin/cos

1+sin/cos

multiply numerator and denominator by 1-sin

we get

1-sin^2/cos-cos sin

take cos common from denominator and 1-sin^2 is cos^2

cos^2/cos(1-sin)

cos/1-sin = RHS
