Thanks you !

you are right there is no such thing, I want to find a surface parallel to the paraboloid given in that equation.

So, if I want to build a paraboloid with a certain thickness L, how would it be done?

Homework Statement I need to obtain the equation of 2 paraboloids separated by a distance L. Homework Equations I think that the equations should be: z_1=x^2+y^2 z_2=x^2+y^2-L The Attempt at a Solution The problem is that when I plot the region between two inequations, x^2+y^2>=z and...

Homework Statement I want to change the integration limits of an integral in cylindrical to cartesian coordinates. For example the integral of function f(r) evaluated between b and R: ∫ f(r)dr for r=b and r=R (there is no angular dependence). For write de function in cartesian coordinates...
