    For the question that said i cant use any graphical or numerixal method to solve, i used identities to find a form where i could factorise it. I did so and then found theta with the 180-theta +360n method. Will i get marks?
    The graphical or numerical methods the examiners are referring to are by using a graphing calculator to read off the line and the numerical is by trial and error.

    You don't actually have to sub a value into the second derivitive. You can just keep it as the value and determine if its max/min from whether it is positive of negative.

    That being said, you don't lose marks for subbing it in.

    How do you do this part?

    Solve: 2^(2x+5) -7(2^x)=0

    Got all the rest of the paper right, but not these 4 marks.
