Converting the Laplacian to Spherical Coords

[@dianaakolzina7668]

Very useful, because most of the books don't tell you how to tackle this problem

Thanks for demystifying the thing...

Sir what should be the value of del such that del ^² is final result which you had proved.

[@robin9740]

That's a matter of looking at the unit vecotrs of x,y,z and r,phi,theta. Keep in mind that the grad-operator = x_hat *d/dx+y_hat*d/dy+z_hat*d/dz. Plug in those unit vectors expressed in the unit vectors for r,phi and theta and take partial derivatives of the x,y and z-unit vectors with respect to r, phi and theta in order to cancel all dependencies on x, y and z.
Good luck!

Perfect. Thanks.
