i need help on these questions please.
1) determine wether each of the followin series is convergent:
a) 2/2^2 + 2^2/2^2 + 2^3/3^2 + ... 2^n/n^2
b) Un = 1+2n^2/1+n^2
does this series in picture converge (sorry did not know how to write in text)
hey thanks alot!
I been working on these today and came across a example on the internet. But there is a process that i don't understand. I have attached a pic from the site and labelled what i don't understand with a red arrow. Hopefully if someone could help i would be very greatful.
how does it cancel?
