These demos are quite elementary in terms of what is possible. If you are interested in more advanced applications, please send a request to information.
A mathematical expression is thought of intuitively as either a constant, e.g. 3.2, an indeterminate, e.g. x, a function with parameters, e.g. tan(x + 2 y) or, recursively, quotients, sums, products, or linear combinations of such expressions, e.g.
(2.31 x3 - 4.3 tan(x + 2 y)) / (y5 -
1).
Note that you will be working with
expressions that have double (floating point)
coefficients.
