The derivative of a function of a variable is a measure of the rate at which the value of the function changes with respect to the change of the variable. It is called the derivative of f with respect to . If and are real ...

In this article is described a simulation of problem of geometric probability in Delphi. This simulation represent an experiment of n samples, where the data we can be included manually or randomly.

Mathematical models are used in the natural sciences (physics, technique, biology) and engineering disciplines (such as computer science), as well as in the social sciences (economics, psychology, sociology, political ...

In this article we show traditional solving of differential equations and using Maple, because they play an important role in many disciplines including engineering, physics, economics, biology, etc. Maple is the world ...
