This is amazing as even mathematicians would learn mathematics from a physicist! Thanks for this gift!

We are fortunate to have teachers like you who explain the subject in an easy manner.

I knew how to derive the Cauchy-Riemann equations by taking the "simple" derivative of f(z) in cartesian coordinates via the limit definition, but the way you did it by constructing a tiny complex vector element e^(i*a) was new to me, and a really illuminating way to demonstrate how strong the CR equations force analyticity. And all this in under 5 minutes! I'm excited to keep watching ☺️❤️

one thing is clear, a suitable cameraman is needed for such a video? Sir, is there any vacancy for a cameraman, then I can attend your class.🙂🙂🙂

That derivation of CR equation is really illuminating. Amazing.

For anyone who is interested, here is a derivation I worked out for the equation at 3:09. It uses chain rule and the Cauchy-Riemann equations. Hope it's helpful!

what's happen to camera in mid of this video, just stuck at one point.

The equation in 12:50 is inverted. The a_n+1 should me in the numerator.

Dear Sir, Your taylor's series is running from zero to infinity, so how can you find the inverse of it upto 'n'(finite), i.e the value of a_{n} what you have shown..???
