Root Finder searches for a root of a continuous function of one variable. User has to specify one point or interval to be used for the initial step. The solver allows finding roots of linear and non-linear functions.
Elementary arithmetic operations only (addition, substraction, multiplication and division) are supported in this free version of the app.
Needs Adobe Air.
