I am having trouble understanding how to find the limit of a summation. I know the formulas and properties but cannot seem to simplify them into a rational form becuase i have never been good at simplifying rational expressions and if there is an easier way to solve them.(adsbygoogle = window.adsbygoogle || []).push({});

I enjoy Summation math and i am wonder two things: 1) can one find the Derivative of a summation and how do you get ride of manipulate problems to get rid of the Summation symbol (if this makes sense).

Thank you.
