Derivative

	DeadLine License: Freeware
	DeadLine is an useful program, especially as an educational support, offering visual indications about the number of roots of an equation and a very precise estimation of those roots. The program solves equations graphically and numerically. It displays the graph of the function and a list of the real roots of the equation. It also includes the option to evaluate the function and its derivative. You can save the results provided by DeadLine and even create projects for future use. Although there is no flawless method for solving equations, the program combines four of the most successful methods in order to deliver you the right answer. And if you don't believe it's true, locate the roots on the graphic and convince yourself. No more problems on getting your homework done. Solve your problems in just a sec. It's easy and, best of all, free. Plus, you get a special gift. Author: Ionut Alex. Chitu\| Date: 31-12-2003 \| Size: 675 KB

	FlatGraph License: Freeware
	Plotting functions (usual and parametric) with more possibilities. Differentiation of any order (with simplification). Construction of tangents to the graph. The simple and clear interface with the detailed documentation and examples of work. The program is designed both for inexperienced and the professional user as in it are combined the intuitive interface and professional functions. FlatGraph allows: - To enter one or several functional expressions of any complexity for display and (or) their differentiation; - To carry out symbolical differentiation for the specified order of a derivative, and also to carry out simplification of the received derivative; - To investigate "alive" changing of various parameters of functions with simultaneous display of new graphs that allows to define influence of parameters of functions on their form; - To use automatic or manual scaling schedules of functions for linear scales; - To display parametric functions, for example, ellisoid, cardioid, Bernoulli lemniscate and other similar graphs (where abscissa and ordinate depend on one parameter 't'); - To solve the equations, system of the equations and inequalities by graphic way; - To define and display a tangent to the graph of function in a point x0 (it is set by the user). FlatGraph has the simple and clear interface, detailed user guide and examples of work. Author: Vitaliy Subbotin\| Date: 19-01-2005 \| Size: 567 KB
