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. |
