well looks like i found a good site to help me with my calc hw.
have a question on power series
the first one i wanna know if i did it right
1) find power series for f(x)=ln(6+x)
ln(6+x) = 1/(6+x) = (1/6) /(1-(-x/6)) = a/1-r
ln(6+x) = sum ar^n = sum (1/6)(-x/6)^n
(-x/6)<1 = -6<x<1
2) Use power series to find the integral of 3/(4-x^2) and then approximate the integral from x=0 to x=.9
kinda stuck on this one there are no examples like this in our book im guessing just do the same thing i did in question 1 right? could someone work this one out.
oh how do you enter in math formulas in on here?
