    Help required with differentiation and integration

    Hello, Ive got a maths exam next week and need help on differentiation as I'm finding it hard to get my head around. I have a few examples of theory questions, if someone could walk me through how to get the solution(s) that would be great, or just the solutions and I could work my way back through the method. Thanks

    I have to differentiate the following:

    f (x) = 2 exp (0.4x 5)

    g (x) = ln (2-3x)

    I (t) = Pb/R (0.2 3e^at)

    y (t) = 3 ln (0.5t 0.4)

    I also have to evaluate definite integrals but would need to scan that examples in, i think the above is more than enough to ask for help with.

    Those look like fairly basic problems. How about showing what you have done and where you got stuck so we can see where you need help?

    these are the solutions I got, are they correct, or on the right track at least?

    f' (x) = 0.8 exp (0.4x 5)

    g' (x) = -3/(2-3x)

    I' (t) = Pb/R ( 3ae^at)

    y' (t) = 1.5/(0.5t 0.4)
