HELP HELP HELP!!
How do you determine the closed form of a summation? I realize that for geometric series the sum is just a/(1r). I can determine the closed form of a nongeometric series by writing out a few sums then finding the pattern, but is there an easier way?
I need an answer ASAP. College placement in a couple of days!

Best ResponseYou've already chosen the best response.1you could actually determine the series's progression and know it's common term and write down as \[\sum_{0}^{n}\]f(x) {i.e a common term} and determine the summation for fewer problems(like those expansion of e! and log(1+x) ) and for others what you are doing is right because for few problems there is no other way except for writing out free sums ........ and when you practice it would help you a lot since few problems are interconnection in pattern and grouping the variables ....... YOU NEED TO REFER FEW BOOKS TO PRACTICE THOSE PROBLEMS FOR QUICKER ANSWERING....BUT PRACTICE TIME WOULDN'T TAKE MUCH OF YOUR TIME
