In this video I continue with my tutorials which cover the necessary vector calculus for classical electromagnetism which is pitched at university undergraduate level. Specifically I build upon video number 8 where I discussed the normal vector. In fact we see that the gradient calculates the normal vector for us.
This video tutorial series covers a range of vector calculus topics such as grad, div, curl, the fundamental theorems, integration by parts, the Dirac Delta Function, the Helmholtz Theorem, spherical polar co-ordinates etc.
Thank you for watching and I hope that this matches your requirements. Please feel free to provide feedback via comments and share with your friends.
