Hi guys, just having some confusions on the Delta-Epsilon proofs for multivariable limit functions.
here is my question:

Apply Delta-Epsilon proof for the Lim (x,y) --> (0,0) of (y^3 + 5x^2y)/(y^2 + 3y^2) to show the limit exists.
The part that has me confused is the y to the power of 3, where as most of the examples I've worked through thus far only contain squared variables.
Any help is appreciated =)

The "y^2 + 3y^2" in the denominator seems odd. Are you sure the problem is typed properly?
 
For original Zeta function, ζ(s)=1+1/2^s+1/3^s+1/4^s+... =1+e^(-slog2)+e^(-slog3)+e^(-slog4)+... , Re(s)>1 Riemann extended the Zeta function to the region where s≠1 using analytical extension. New Zeta function is in the form of contour integration, which appears simple but is actually more inconvenient to analyze than the original Zeta function. The original Zeta function already contains all the information about the distribution of prime numbers. So we only handle with original Zeta...
