1. The problem statement, all variables and given/known data This question is in my exam review problem from my complex analysis class. Compute f(100)(0)/100!, where f(z) = 1/(1+i-sqrt(2)z). (f(100)(0) means the 100th derivative of f evaluated at 0.) 2. Relevant equations Cauchy's integral formula might be helpful. The answer to this question is -1/(1+i). 3. The attempt at a solution I thought about using Cauchy's integral formula, but it seems like I need to rewrite f(z) so that I have singularity at 0... or maybe I'm completely missing out. Thanks!
