Exploring different combinations of terms, we derive several approximations to compute the second order derivatives of complex-valued function. Several second order of accuracy finite differences to calculate derivatives are proposed. Error analysis in test examples is carried out by using Matlab program. ru_RU dc.language.iso other ru_RU dc.publisher Ye.A.Buketov Karaganda State University Publ. ru_RU dc.relation.ispartofseries Қарағанды универисетінің хабаршысы.
