Best ResponseYou've already chosen the best response.0That is, I'm asking if it's only the end points you're having trouble with.

Best ResponseYou've already chosen the best response.0while you're hear though.... how do you do term by term multiplication in a series? i have to find the first four nonzero of the MacLaurin series sinx *cosx

Best ResponseYou've already chosen the best response.0Anyway, the series is convergent for x such that\[\lim_{n \rightarrow \infty}\ \left \frac{(x2)^{n+1}/\sqrt{n+1}}{(x2)^n/\sqrt{n}} \right<1\] by the ratio test, and then check for convergence at each of the end points, x=1 and x=3. Convergent for 1 by alternating series test, and nonconvergent for 3 by integral test, say.

Best ResponseYou've already chosen the best response.0\[\left( \sum_{}{}a_n \right)\left( \sum_{}{}b_n \right)=\sum_{}{}c_n\]where\[c_n=\sum_{k=0}^{n}a_kb_{nk}\]

Best ResponseYou've already chosen the best response.0\[\sum_{n=0}^{\infty}c_n=\sum_{n=0}^{\infty}\left( \sum_{k=0}^{n}a_kb_{nk} \right)\]

Best ResponseYou've already chosen the best response.0Well, it depends on your software and machinery. They're not all the same. You have to make sure your scanner is connected to your computer, either through a cable or wireless, and use the appropriate software.
