The first problem is that you have a function in terms of and , but telling it to make go to a value.
What is ?
I am having trouble with
Limit of as z->2i
i set it up at lim 2x as x->0 + i lim y^2 as y->2. so i get 4i as my limit but when i plug 2i directly i get -4i... is this right because of how the complex plain is defined?? or am i completely wrong thinking the limit is 4i? any help would be awesome!
