[solved]Trigonometry problem

Post by Sujith on Sat May 08, 2010 2:47 pm

Does anyone know how to do this one -
PROVE THAT:-
cos A (1 + cot A) + sin A (1 + tan A) = sec A + cosec A
I tried substituting cot and tan to sin and cos but no answer
Code:
cos A (sin A + cos A / sin A) + sin A (cos A + sin A / cos A)
