[tex]\int x {(C - x^{2/3})}^{3/2} dx[/tex]
Any ideas?

Nah, you don't need to be an oracle to know it.gulsen said:Yup, thanks! :)
But isn't this substitution very subtle? Am I an oracle to guess it instantenously in an exam!?
Have you looked closely at the fifth post of this thread, daveyp225??daveyp225 said:even better...

A surface integral is a mathematical concept used in multivariable calculus to calculate the flux, or flow, of a vector field across a surface. It is similar to a regular integral, but instead of integrating over a one-dimensional curve, it integrates over a two-dimensional surface.
The general formula for solving surface integrals is: ∫∫F(x,y,z) · dS = ∫∫F(x(u,v), y(u,v), z(u,v)) · ||ru x rv|| dA, where F(x,y,z) is the vector field, dS is the surface element, r(u,v) is the parametric representation of the surface, and ||ru x rv|| is the magnitude of the cross product of the partial derivatives of r(u,v).
To solve a surface integral with a given function, you first need to determine the limits of integration by setting up a double integral with the parametric representation of the surface. Then, you can plug in the given function into the formula and solve the double integral using standard integration techniques.
The given function is the integrand of the surface integral and represents the flux of the vector field across the surface. It is related to the surface because it is integrated over the surface to calculate the total flux. The function may also be used to determine the direction and magnitude of the flux at each point on the surface.
Yes, you can use any coordinate system as long as it properly represents the surface and allows you to calculate the necessary limits of integration. Common coordinate systems used for surface integrals include Cartesian, polar, cylindrical, and spherical coordinates.
