    Tried to make this as simple as I could. Sorry if the images are eye hurting.




    I'm sorry I forgot to change the limit when I substituted the variables in the first one but other than that it is correct.
    A few trivial things you might ask, I wanted to clear these up

    • Anything raised to the power 0 equals 1 (=> log 1 must be 0)
    • e^x is just the anti-logarithm (with base e) of x, so the anti-logarithm of a log is just the parameter of the log itself.

    Oh yeah sorry, forgot to proofread. So the required integral is e-2 and not e.
