Hi guys, I'm new to this forum, I am a mechanical engineering student, I am actually taking Multi-variable Calculus (Calculus III, on my college) this semester and I'm having a lot of trouble proving the limit of a multivariable equation using the epsilon-delta technique.
Example:
lim (3xy^2)/(x^2+y^2) x->(0,0)
I don't even understand what is about, I look the limit of the equation along x and y-axis y=mx and y=x^2 and found L=0 but how do I prove it is really 0.
The book show something about epsilo-delta technique but say's nothing about how using this technique, it look kind of random.
Thanks a lot Link-
PS. Sorry for my english, I am not a good english speaker or writter but at always I do my best
