    Deriving the volume element in spherical coordinates

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A differential of volume is given by:

    dV = r^2*sin(theta)*dr*d(theta)*d(phi) can you derive this for me i.e. using a differential of volume and spherical coordinates show how this equation is arrived at?

    r is a radius, theta is the angle in the x-y plane and psi is the the z-y plane

    Please show a diagram

    Here is the derivation, or should I say the two derivations.

    The first is the straight hard-core multivariable calculus approach in which one has to calculate the Jacobian of the transformation.

    The ...

    The 3 pages solution demonstrates how to utilize the Cartesian to Spherical coordinates conversion to obtain the infinitesimal volume element in an analytic manner.
    then it demonstrates how to get the same expression using graphics.
