Find Roots of Real-Valued Functions
Type a new function and study its zero crossings. The info panel will show the numerical values of the roots. Open the info panel by pressing Ctrl-i or from the menu bar Inspector->Geometry->Info.
Controls:
| Function expression textfield | Type the expression of a function whose zero crossing you want to study. Use any combination of mathematical functions described in Expressions.html. |
| Slider "xMin" | Lower bound of definition interval of the function. |
| Slider "xMax" | Upper bound of definition interval of the function. |
| Slider "Discr of Polygon" | Number of equidistant samples being computed in the definition interval. The function will be evaluated at sample points to find starting values for the searching algorithm. |
