Hmm. So it is possible to get to -3i/16 from where I've gotten or have I made a mistake in my logic? Cancelling out the brackets that equal zero on the top and bottom of each fraction doesn't seem to help (and I don't think you can do that anyway).
The reason this differential has to be done is...
Homework Statement
Find the solution of the following differential in the limit z -> i/2:
Homework Equations
Quotient rule, product rule.
The Attempt at a Solution
I found the first derivative using the quotient rule, with the answer as two fractions. I then took both fractions and...
