Taylor Series

  1. Mar 25, 2004 #1
    Find the 4th term of the Taylor series centerd at x=1 for f(x)=ln(x+1)


    Plug in 1:

    What do I do next? (Also, is the 4th term the 4th term starting with f(x)? or the 4th derivative?)

    it would be easier to start with the series for 1/(1+x) which is close to the geometric series. then integrate that to get the series for ln(1+x). then just look at the correct coefficient.

    Don't use decimals, please, your teacher should be happier that way. And the 4'th (non-zero) term is exactly that, write down the taylor series, and pick out the 4th term in it (the x^3 term here).
