    1. The problem statement, all variables and given/known data

    find maclauren series for: logx and arctan

    2. Relevant equations

    heres the maclauren series:

    3. The attempt at a solution

    to solve these, do i need to keep applying the maclauren series formula like i would for sin or cos?

    in other words, taking the derivative for logx and arctan, if so, can someone start me out with the derivatives, i don't know them.

    also is e^x the same as xlog(e) ?

    Well, what do you know. Do you not know the derivative of log(x)?

    To calculate the derivative of arctan(x), try letting y=arctan(x) noting that now x=tan(y), and then differentiating both sides wrt x.
    Erm, no, what makes you think this?
