secA - t a n A = \frac{cos A}{1 + sin A}

\frac{t a n A + s e c A - 1}{t a n A - s e c A + 1} = \frac{1 + s i n A}{c o s A}

prove that inA-cosA+1÷sinA+cosA-1=1÷secA-tanA using identity sec2A = 1+tan2A

\frac{1 + s i n A}{1 - s i n A} = s e c A - t a n A

\frac{s i n A - 2 s i n^{2} A}{2 c o s^{3} A - c o s A} = t a n A

\sqrt{\frac{1 + s i n A}{1 - s i n A}} = s e c A + t a n A
