Homework Statement
In calculus 1, honestly, I never understood this as it just doesn't make sense. Now in multivariable calculus, it still doesn't make sense. After all these engineering, math, and science classes, I still cannot figure these problems out, and it pisses me off! I would appreciate it if someone could explain this example to me...
Evaluate
$$\lim_{(x,y)\rightarrow (0,0)} \frac{5x^2y}{x^2+y^2}$$
Homework Equations
The Attempt at a Solution
This is an example problem, the book does not explain this well at all. The answer they get is: You can choose ##\delta = \varepsilon /5## and conclude that the limit = 0.
I don't even see how they just (seemingly) magically conclude that.
Any help is appreciated.
