    Need help with Maclaurin Series problem

    Need help with Maclaurin Series problem-capture.png

    How can i recognize the function?

    If the first problem (a) is

    f(x) = summation of x^(3n+2) startinng from n=0, what is the function then? I know that x^n is geometric series function, but im unable to conclude the function

    Re: Need help with Maclaurin Series problem

    I toyed with common series a bit and came up with

    $\sum \limits_{k=0}^\infty ~(-1)^k x^{3k-1} = \dfrac{x^2}{1+x^3}$

    Look at the common Maclaurin series templates.

    You may have to use a power of $x$ rather than just $x$

    You may have to adjust things by dividing or multiplying by $x$

    Use Wolfram Alpha Series function to test out your hypotheses.

    Series[f(x), {x, 0, n}]

    will give you $n$ terms of the series of $f(x)$ about $x=0$
