it was awesome, really love maths
2. ### Is there any way to calculate this integral?

YESSSS DONE!!! THANKS MEN AWESOME
3. ### Is there any way to calculate this integral?

##\displaystyle{\int_0^R {r³\over \sqrt{R²-r²}\,}\int_0^{\pi\over 2}{\sin \phi\cos \phi}\ dr\;d\phi}## ???

i edit it
5. ### Is there any way to calculate this integral?

$$R\iint {xy\over \sqrt{R^2-(x^2+y^2)\,}} \ dx dy=\int {r³\over \sqrt {R²-r²\,}} \ dr...$$
6. ### Is there any way to calculate this integral?

so difficult.. i dont know
7. ### Is there any way to calculate this integral?

o-R for x right?
8. ### Is there any way to calculate this integral?

could you write it ?
9. ### Is there any way to calculate this integral?

this way of solve it is so difficult
10. ### Is there any way to calculate this integral?

but ##x²+y²=R²## so ##z= \sqrt{R^2 - (x^2+y^2)\,}=0##
11. ### Is there any way to calculate this integral?

I will try it, thanks!
12. ### Is there any way to calculate this integral?

my problem is to resolve it with surface in this form: G(x,y,z)=x^2+y^2+z^2-R^2=0 the theory is or equivalent or the real problem is in the f(x,y,z(x,y)) or the other equivalent
13. ### Is there any way to calculate this integral?

yes i am interested. here is the resolution by put the sphere in parametric form r(u,v)
14. ### Is there any way to calculate this integral?

Rxy is the projection of S in the plane xy.
15. ### Is there any way to calculate this integral?

here is my problem but in the other form is resolved yet
