Copying function in variable

Writing functions:

setformula(variable, formula)

Variable variable is copied the formula. In this case, the variable which acts as a container for the formulas, for example:

setformula(y, x^2-4);

The same effect will be under the command:

&y=x^2-4;

The function of assigning a formula to a mathematical function to a separate variable is a mechanism that allows you to assign the value of a function to a single variable for subsequent use in a program. With this function, you can effectively work with mathematical functions such as sine, cosine, degree, and many others.

The basic principle of the function is to accept the values of a mathematical function as input parameters and assign them to a separate variable. This makes it possible to use the result of the function in the future in any part of the program where the use of this value is required.

The function of assigning a formula to a mathematical function to a separate variable must accept an input parameter representing the value of the function. Next, this value is assigned inside the function to a new variable created specifically to store the results of the function. A new variable can be named arbitrarily, but its name must correspond to the meaning and purpose of the function.

The advantages of using the function of assigning a formula to a mathematical function to a separate variable are to increase the flexibility of the program and the convenience of working with the results of calculations. Thanks to this function, function values can be stored and used in any part of the program without having to recalculate the function. It also allows you to improve the performance of the program and reduce the amount of memory used.

In conclusion, the function of assigning a formula to a mathematical function to a separate variable is an important programming tool that ensures effective work with mathematical functions. Using it allows you to save the results of functions and easily use them in the program, which makes programming more flexible and efficient.
