Hello. Consider the following simple examples of FindRoot application. FindRoot[Sin[x] == 2, {x, I}] {x -> 1.5707963267948966 + 1.3169578969248168*I} FindRoot[Sin[x^2] == 2, {x, I + 1}] {x -> 1.3454777060580754 + 0.4894016047219337*I} FindRoot[Sin[x^2] == 2, {x, 3*I + 2}] {x -> 0.3004695589886017 + 2.1914997002654357*I} Is it possible for FindRoot (or in general in another way) to search for solutions in the complex plane in an particular domain e.g. searching in the domain that is made by the lines Re[x]=a1, Re[x]=a2 and Im[x]=b1, Im[b]=b2 ? I really appreciate any assistance. Regards Dimitris
