GOOD QUESTION

NICCHE OPEN THE DENOMINATOR

DIVIDE NUMERATOR ANS DENOMINATOR BY COS2X
THEN PUT TANX = T AND MAKE THE REQUIRED SUBSTITUTIONS

I HOPE THIS HINT IS SUFFICIENT[1]

:) Well mani ur original pic is amazing ..........
But I have tried that .... dividing by cos2x does'nt work . simply beacause there is x2 in the numerator....and in the denominator ...

Any other method to solve this ... anyone....
