How do I evaluate the infinite series (2^n)/(n!) from n=0 to infinity?
(I don't know how you put the little E symbol and all that in so I had to write it out.)
I already found that it converges to 0 using the ratio test, but I don't know quite how to evaluate it.
Any help would be mondo...
thanks - i just don't understand physics - if i would have known that i was going to have problems, i never would have taken it - my main problem is that my teacher doesn't teach - he just kinda presents the material, and i don't get it, so i have to try to teach myself, which is really hard...
how exactly do I use the tangential velocity to find the height?? Sorry if I sound like I'm dumb or something, but I don't really get physics too well...
Hey Everyone! I don't quite understand how to figure this out...Any help would be greatly appreciated!
