Main Question or Discussion Point
Hi,
I was trying to form a summation for ##y_1## and have provided a solution but do not quite understand how it was formulated. I was trying to look for general patters and besides a ##(1)^{n+1}x^2n## in the numerator, I'm a little lost on how to find a general term for the denominator. Also, is the pi just another summation symbol inside of the sigma summation? Does the symbol have any other meaning? Any help regarding how to approach this questions would be greatly appreciated!
