""If a fn. satisfies CR eqn. it does not imply fn. is analytic"". counter : f(z) = (|xy|)^(1/2) satisfies cr eqn at (0,0) but not differentiable hence not analytic. but since all partial derivatives are continuous in the examples taken therefore these examples are analytic also. thank you
We can't say that a given function is analytic when it is just satisfied cauchys equations.We will have to show that the derivative exists also.. But when my function is not satisfied cauchys then not diff...that's true..
My test is just 35 mins from now.. and this video is really well explanatory.. thank you ❤
you are welcome
waaw; your explanation is perfect, and I like how you took your time
Glad you liked it!
Good explanation. 😊
big fan...... sir
😍😍🥰😆
كل التوفيق إن شاء الله 💙
Good lecture method
thank you so much sir 🥰you just save me 😇😇😇
Very good explanation 🫡
Amazing!
amazing video thanks
Thank you too!
