Displays the real and imaginary parts of complex functions, or conformal transformations. Bulit-in functions include sine cosine tan sinh cosh exp and Log, and these can be combined to produce a wide range of expressions such as tan(z-2*i) - sin(z*z). These expressions can be displayed in terms of their real and imaginary parts, or used to tranform shapes from the z to the w plane.
Functions can be plotted along 'slices' so that the value of the real or imaginary parts of a function along any line in the z plane can be displayed.
Where appropriate the integral of a function along a path can be calculated numerically and displayed . Argand.

Displays graphs of algebraic functions in a variety of forms. These include polar and cartesian co-ordinates, parametric and intrinsic functions. A wide range of functions are built-in, from simple trig and hyperbolic functions to things such as the ceil and gamma functions. On-screen HTML help is bulit-in.
Functions can be defined such as
f(x)= 1 + x
These can be of unlimited complexity, and can refer to other functions such as
g(x) = f(x) + 2*x
Other variables can be set up, so we can define for example
f(x) = m*x + c
and then vary m and c and see the change to the graph.
It will also handle differentiation, integration, sums and products of series. It will deal with Maclaurin and Fourier series, such as a Fourier approximation to a square wave.
The graph limits can be altered in various ways...

Displays lines and surfaces defined algebraically in 3D space in many forms, including z=f(x,y), cylindrical polar coordinates, and parametric definitions with one (giving a line) and two (surface) parameters. View controls move the viewpoint through 3D space, using keyboard and mouse. There are options to display a surface, a mesh or a combination. The number of 'steps' on each edge (level of detail) can be controlled.
The defining expressions include a very wide range of forms : polynomials, trig, hyperbolic exponential and logarithmic, rational expressions and series sums and products. Gauss.
