I can't explain how much irritating it sounds when the lecturer was saying (del u del x ) as (do u by do x) . Come on, you are saying that and everyone listening, so, if you say like this then what will they learn? moreover this derivative is an operator, so we say ( del u del x) not ( del u by del x) . I agree that one may have different accent and pronunciation but.......this is not expected. Other than this, the lecture is well and good.
the geometrical interpretation part is very interesting. thank u sir.
Should f'(0)=Re(z) instead of 0 at 21:16?
Because lim_(h-->0) (f(z+h) - f(z))/h is equal to lim_(h-->0) (zRe(z)/h) + Re(z) = Re(z) when z=0.
z=0 in that case so Re(z)= 0 . Z is absolutely 0 but h is approaching 0 .
The derivative exists only for z=0,hence if f'(0) = Re(0) =0
Thank you sir. Nice introduction to complex derivatives.
Thank you very very much , sir !! you are just awesome !!
Sir is awesome but nptel is fucking awesome
Thank you so much sir, it's easy to understand for an average student too
