I've got to calculate:
[tex]\displaystyle\int_0^1\displaystyle\int_0^x \sqrt{4x^2-y^2} dy dx[/tex]
Homework Equations
The Attempt at a Solution
I've tried the change of variable:
[tex] \displaystyle t=4{{x}^{2}}-{{y}^{2}}[/tex] but it doesn't get better. I've also tried polar coordinates but it is not convinient either. Do you know a convenient change? I've been trying to figure it out for a long time.
** I also tried changing the order of integration but no results.
Thanks!
