Abstract
The present paper is presenting a review of our applications of computer algebra systems (CAS) [10, 11, 40] to different problems: for analysis of random phenomena in nonlinear dynamical systems and primary education in this sphere; for finding of control functions and for mathematical modelling of a mechanical objects movement. To archive final results in various tasks it is required to process a large number of mathematical calculations. Moreover the complexity of investigated objects requires to automate a procedure of model construction that results in the necessity of CAS using (together with numerical accounts) at all stages of scientific research.
