| Derive
is the trusted mathematical assistant relied upon by
students, educators, engineers and scientists around
the world. It does for algebra, equations, trigonometry,
vectors, matrices and calculus what the scientific calculator
does for numbers. 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
everyday mathematical work, Derive is a tireless,
powerful and knowledgeable assistant. For teaching
or learning mathematics, Derive gives you the freedom
to explore different mathematical approaches easier
and faster than traditional methods.
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.
Derive applies the rules of trigonometry, calculus,
matrix algebra and vector calculus to solve your toughest
math problems.
 Mathematical worksheets
Create, edit, print and save your analyses, solutions
and explorations in richly formatted worksheet documents.
Mathematical worksheets can include 2D and 3D plot
images, text and OLE objects. Equations, matrices
and other math expressions are shown in their true
mathematical format. Derive makes it easy to document
your complex math work and share your ideas with colleagues.
 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.
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. Mathematical expressions
are displayed and printed in the standard 2D format.
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. Utility
files are automatically loaded on demand, so these
functions are always available for use.
 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!
