we operate divergence only on vectors while laplacian is operated on scaler

In laplacian operater the function is producted(multiplied) two times by the del operator and in divergence it is only once. Generally spherical coordinate system is used to find ...

basic diff is that divergence is 1s order derivative.. while laplacian is second order so that.. formulas are different -2 ...best regards

Laplacian is double divergence means Laplacian is divergence of ( divergence of F)... that's why formulas are different for Laplacian and divergence...

and the simple form is operate the divergence on gradient of some scaler fxn

and the basic difference is that divergence is 1st order derivative while laplacian is second order

divergence is simply dot product of del with some vector and laplacian is divergence of gradient of some scalar function(del square). Divergence and laplacian are completely differ...
