oh yea. the x^2, which is why I must use= (x/2)^2 But, where do I go from here: = ??
Originally Posted by saiyanmx89 oh yea. the x^2, which is why I must use= (x/2)^2 well, you could distribute the power. what do you think it would look like then?
could I use the Ratio Test on

so, by using the Alternating Series, I can take the absolute value of the function leaving me with (x^2/4) or (x/4) ??? I'm not sure which...
