Homework Statement
Find the Maclaurin polynomial for P(6)X for 1/(1+2x2) about x=0
Homework Equations
I'm pretty sure I need to use the Maclaurin polynomial for 1/(1-x)= 1+x+x2+x3+...+xn +O(xn+1)
The Attempt at a Solution
I simply rewrote as 1/(1-(-2x2)) then proceeded to sub and expanded. The answer was not what I expected and not what I got. Apparently it's suppose to be 1-2x2+4x4-8x6. Can anyone expain to me why is there only four terms?
