Best ResponseYou've already chosen the best response.1That's called a series. The symbol is called Sigma A sequence means you do not add up the terms, a series means you do. There are a number of series related to trig functions, but I am guessing you mean the Taylor series expansion of sine and cosine...\[\cos x=\sum1\frac{x^2}{2!}+\frac{x^4}{4!}\frac{x^6}{6!}+\dots\]\[\sin x=\sum x\frac{x^3}{3!}+\frac{x^5}{5!}\frac{x^7}{7!}+\dots\]right?

Best ResponseYou've already chosen the best response.0something like that but that goes into calc very fast when i just grabbed a trig book lol the whole problem when 6 64 ∑ 2 ^k k=1 this is what the whole thing (problem) looks like

Best ResponseYou've already chosen the best response.1Most functions f(x) can be written in terms of Taylor series\[\sum_{n=0}^{\infty}\frac{f^{(n)}(a)}{n!}(xa)^n\]However the problem you posted\[64\sum_{k=1}^{6}2^{k}\]is a very different one, and has no relation to trig functions that I personally know of.

Best ResponseYou've already chosen the best response.0it will be a while before i get to taylor series i only got to limits i am back tracking on trig

Best ResponseYou've already chosen the best response.1is that series that I posted second the correct one?

Best ResponseYou've already chosen the best response.0i was just focusing on what you said not the problem itself that if was or not part of trig at the moment then i looked at the calc part so ty very much :)
