    Right, I think I may have mislearnt my differentiation of somethings.

    If I were to differentiate 4e^2t I would get 8e^2t right?

    Because my teacher does past papers answers and he's differentiated it to: 8e^2t x 2 = 16e^2t

    Because as far as I knew to differentiate e you just times the constant by the differential of the power :X.

    Which is right?

    Your right. if y=e^nx then, dy/dx=ne^nx (where n is a constant)

    Thanks. I thought so, that was doing my head in. He has a tendency to rush past paper answers as WJEC tries to charge for them and he makes a few mistakes every now and then.
