Watch & download e infinity approaches what MP4 and MP3 now. You can download free mp3 or MP4 as a separate song, or as video and download a music collection from any artist, which of course will save you a lot of time.
Do you like voice explanation then watch this video on a new, easier and different version of the proof. If the base of exponential function is greater than 1 then its limit does not exist as it approaches infinity. In this video i go over the exponential function y = e^x and write it as a limit.
Limit (1+1/n)^n = e as n approaches to infinity proof. Earlier proved number e limit which can be simply considered.
