## Homework Statement

Iv been given the complex potential equation ..iv been trying to split it into real and imaginary parts so i can find the streamfunction and potential for it...however the ln is making it difficult

## Homework Equations

## The Attempt at a Solution

iv tried taking out a factor of two from 2i +4 and raising it to the ln part...so i get ln (x+iy)^2...i expanded that but i still got imaginary parts inside

so i was wondering if anyone knows any other ways to split the equation into imaginary parts and real parts
