Example of a function that satisfies the Cauchy-Riemann equation.
In this lecture Dr. Kamran Khan takes his time to solve a problem that satisfies the Cauchy-Riemann equation.
The question says, show that the function
f(z)=x3(1+i)−y3(1−i)x2+y2 satisfies the Cauchy-Riemann equation at z=0 but f′(0) does not exist.
