The approximated equation root

Parent Previous Next

Allows the user to create an approximation root of an equation on an interval [a; b].

This root will be characterized by a name, the name of the unknown, an equation and the values of  a, b,  and uncertainty.

MathGraph32 creates a function by subtraction of the two members of the equation. Let's call f this function.

The solution will exist only if f(a) and f(b) are of different signs.

You are responsible of the existence and unicity of the solution on the given interval.

To be noticed :

       In no way the root is an exact solution..

       Asking a very high precision may result in slowing the update of the figure.
