by y >= 0; z = -17; z = 17. Evaluate
\iint xy^2z^2
Homework Equations
The Attempt at a Solution
So I use the equation x^2 + y^2 \leq 9, meaning that r goes from 0 to 3
Since y...
Evaluate the limit or prove that it does not exist..
f(x,y) -> (0,0)
3xy/((x^2)+(4y^2))
The attempt at a solution:
Set x to 0 and you get 0
set y to 0 and you get 0
set y=x and you get 3x^2/5x^2 = 3/5
This means that limit does not exist.
Is this correct?
If this is correct, how...
