Determine the gradient in spherical coordinates?

a href="http://mathworld.wolfram.com/SphericalCoordinates.html" rel="nofollow"http://mathworld.wolfram.com/SphericalCo…/a has the formula for the gradient in spherical coordinate. Normally this formula will be provided on tests and never memorized (or needs to be on your formula sheet). Your text should cover this. Be aware that not everyone defines the angles in spherical and cylindrical coordinates in the same way, so use the notation in you text which is likely to match math worlds definition. Taking the derivatives are straight forward and just add the extra terms per the formula provided.
