So the Laplacian of a scalar is divergence of the gradient of a scalar field, and it comes out to the double derivative of the field in X, Y, and Z.(adsbygoogle = window.adsbygoogle || []).push({});

My book says the Laplacian of a vector field is the double derivative of the X component of the field with respect to X, the double derivative of the Y component with respect to Y, and same with Z.

I'm not sure how this comes about from the definition of the Scalar Laplacian.
