Derive 5 Derive is the trusted mathematical assistant relied upon by students, educators, engineers and scientists around the world. It eliminates the drudgery of performing long and tedious computations. You can easily solve both symbolic and numeric problems and see the results plotted as 2D graphs or 3D surfaces. For teaching or learning mathematics, Derive gives you the freedom to explore different mathematical approaches easier and faster than traditional methods. Now with Derive 5 you can: deal easily and quickly with all your calculations in algebra, equations, trigonometry, vectors, matrices, and calculus create and save Math worksheets solve both symbolic and numeric computations - ideal for engineers, financial math, statistics, physics, and other applications display results with extensive 2D and 3D graphics capabilities
	"Derive is...a powerful but uncomplicated package, well established and reliably supported... Version 5 remains faithful to the original concept but features significant new updates with improved Windows compatibility." Scientific Computing World, August/September 2000   * Click here for more REVIEWS of Derive Contact us for a free Derive 5 demo CD to see the advanced capabilities of Derive for yourself. Special Educational prices available for Lab packs.
	Powerful Computer Algebra System (CAS) tool Derive algebraically simplifies, expands and factors expressions. Equations and systems of non-linear polynomial equations can easily be solved, yielding their real and complex solutions. Numeric operations are performed exactly with no round-off error and the results can be specified to thousands of digits of precision.

2D Plots Create multiple 2D plots to analyze and explore equations in both Cartesian and polar coordinate systems. Control the aspect ratio, scale and axis definition of your plot, and optionally view the real and imaginary parts. Trace the graph and view precise coordinates of points on the curve. Derive can even plot Boolean combinations of inequalities involving two variables! Easy to create and analyze 3D surfaces Rotate and zoom multiple shaded 3D surfaces in real-time. 3D surfaces can be created using functions defined parametrically and as sets of data points. Surfaces can be displayed in rectangular, spherical and cylindrical coordinate systems. Determine coordinates of points on surfaces using movable highlighted cross lines. 3D surfaces can be annotated with descriptive text and exported in popular formats such as TIFF, JPEG, BMP for use in other programs. Mathematical worksheets Create, edit, print and save your analyses, solutions and explorations in richly formatted worksheets. Mathematical worksheets can include 2D and 3D plot images, text and OLE objects. Equations, matrices and other n-bath expressions are shown in their true mathematical format. Derive makes it easy to document your complex math work and share your ideas with colleagues. It's easy to use! Math symbols and Greek letters are just a click away with dockable toolbars. Toolbar buttons make it easy to create matrices, do integration and differentiation, determine limit values, and more. Derive includes an extensive library of utility files that define functions for solving first and second order ordinary differential equations (both exactly and numerically), and for computing Bessel, Fresnel, elliptic integrals and other special functions.
