The test of function variable dependence

Parent Previous Next

This object purpose is mainly for displaying inline figures for the teaching of calculation.

It's goal is to know if a function of one, two or three variables depend on one of it's variables.

The test is made without simplifying the calculation of the function.

The value returned is 1 if the formula depends on the chosen variable and else 0.

For example, a function defined by f(x,y) = x^2 +2*y - x^2 will be considered dependant of x and y.

But a function defined by f(x,y,z)=x^2+y will be considered as non dependent on z and dependent on x and y.

To define such an object, use menu item Calculation -New real calculation - Test of dependance function - variable, the choose the function and the variable in the dialog box that pops up.
