Recently I read about Cauchy-Riemann equations and I got a doubt in that.(adsbygoogle = window.adsbygoogle || []).push({});

I can understand the derivation of it but I couldn't understand the basic assumption with which you derive that.

Why should the limit give the same value for both real and for imaginary axis?

I hope you can understand the question. If you can't understand the question just reply.

Thanks a lot
