Hello again,

I am trying but it is really hard learning this stuff on your own. Never gonna take a calc course online again :\.

This it he question, I am currently stuck on.

Where is the function analytic?

For now could someone just help me with the derivative? I am in the process of figuring out Couchy-Rieman equations.

Is the derivative only present if u/ x = v/ y?

just for my understanding in the equation there is no derivative because u/ x = 0 and v/ y = 1?

Thanks

Rioch
