Program Mathcad is the powerful and effective instrument of the quantitative representation and investigation of analytical models.
Singularity of this program is presence of the "clever" worksheet field, allowing to put to a Mathcad of the task and to gain solutions in the form, close to the customary mathematical.
Mathcad presence in an arsenal of the researcher or the engineer does not cancel necessity of knowledge him of mathematics. The Mathcad is the instrument of the investigator, it is no more and not less. But existence of such instrument allows to look in a new fashion at the concept of learning of mathematics in high schools, and at school. Now the mathematician for engineers can state, not adding, as earlier, excessive importance to technical details of the demonstration of different positions and obtaining of outcomes, for example determinations of prototypal. At the same time, the Mathcad allows to give more attention to setting of tasks and the analysis of outcomes of their solution. But it is given nothing free of charge: instead of learning of details of a mathematical apparatus now it is necessary to study singularities of implementation of solutions in a Mathcad!
Advantages of Mathcad:
2.2.1. The solution of the equations and plotting. |
The application to the article "About methods of description of linear systems" |
2.2.2. About calculation and plotting of frequency characteristics of linear systems in Mathcad |
Simple, but effective methods of compact plotting of the frequency characteristics, essentially speeding up run time are observed. Naturally-logarithmic form of representation of Mihajlov's and Nyquist's hodographs is offered, allowing compactly to present the hodograph in major frequency band at saving of correct mapping of arguments. 12.04.2006 |
