    I can't give you a step by step solution because thats against TSR rules but I can give you a hint.

    You don't know how to integrate tan2x, only how to differentiate it. What you could do is write it as sin2x/cos2x and use the substitution u=cos2x

    Hope this helps

    Try using this:

    \frac{d}{dx}(ln(f(x))) = \frac{f'(x)}{f(x)}

    tan2x = (sec2x X tan2x)/sec2x
    think about the derivative of ln(sec2x).

    C4 ex1c ques3a) ? lol
