## Homework Statement

lim (x,y)[itex]\rightarrow[/itex](0,0) f(x,y)=2*x/(x[itex]^{2}[/itex] + x +y[itex]^{2}[/itex])

## Homework Equations

used different paths like y=k*x ,where k is a constant and y=k*x^2

## The Attempt at a Solution

Got an answer 2 but solution says does not exist. Can anybody convince me that why limit does not exist,

**without using polar form**.

I am currently studying in 1st year of college.
