The manufacturer of scientific calculator student tells you that the calculation process mainly includes three stages: the establishment of the mathematical model, the establishment of the calculation method for solving, and computer realization.

The manufacturer of scientific calculator student tells you that to establish a mathematical model is to establish a series of quantitative relationships, that is, a set of mathematical formulas or equations, for the object under study based on the relevant subject theory. Reasonable simplification of complex models is an important measure to avoid excessive computation. Mathematical models generally contain continuous variables, such as differential equations and integral equations.
The scientific calculator student manufacturers tell you that they cannot be processed directly on a digital computer. To this end, the problem is first discretized, that is, the problem is transformed into a discrete form containing finite unknowns (such as a finite algebraic equation system), and then a solution method is found.
The manufacturer of scientific calculator student tells you that computer implementation includes a series of steps such as programming, debugging, computing, and analyzing results. The development of software technology provides suitable programming languages ​​(such as Fortran, and ALGOL) and other software tools for scientific computing, which greatly improves work efficiency and reliability.
The above information is the scientific calculator student manufacturer's introduction and analysis of the calculation process, hope it helps you.
