	Orneta Calculator for Smartphone 2002  License: Freeware
	Orneta Calculator is a simple and easy to use application that acts like a standard scientific handheld calculator for Windows Mobile based Smartphone's. Just use your Smartphone when a separate handheld calculator is too much. Enjoy the simple access for quick calculation of difficult problems. Solve your math and science problems at work, school, the lab, or even on the road. You can perform any of the standard operations for which you would use a calculator, including basic arithmetic, such as addition and subtraction, as well as functions found on a scientific calculator, such as logarithms and factorials. It even has memory functions to save and recall the solutions. The history of all of the calculations and functions are displayed on the screen which can be scrolled for easy access. Advanced Features: Add, Subtract, Multiply, and Divide Save and Recall Memory functions Full degrees, radians, or grads calculation Percentage calculation and conversion Square Root, Sine, Cosine, Tangent Arc Sine, Arc Cosine, Arc Tangent Author: Orneta| Date: 27-05-2003 | Size: 50 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
