# Maple computer algebra system

Maple is a general purpose commercial computer algebra system. It was first developed in 1981 by the Symbolic Computation Group at the University of Waterloo in Waterloo, Ontario, Canada.

Since 1988, it has been developed and sold commercially by Waterloo Maple Inc. (also known as Maplesoft), a Canadian company also based in Waterloo, Ontario. It is marketed as "the essential productivity tool for every technical professional." The current version is Maple 9.5.

## Introduction

Maple is an interpreted, dynamically typed programming language. As is usual with computer algebra systems, symbolic expressions are stored in memory as directed acyclic graphs.

Since Maple 6 the language has permitted lexically-scoped variables.

## Example Maple code

The following code computes an exact solution to the linear ordinary differential equation $\frac{d^2y}{dx^2}(x) - 3 y(x) = x$ subject to initial conditions:

dsolve( {diff(y(x),x,x) - 3*y(x) = x, y(0)=1, D(y)(0)=2}, y(x) );

## Versions available

Maplesoft sells both student and professional editions of Maple, with a substantial difference in price (e.g., US$99 compared to US$1,995.00, respectively).

Recent student editions (from version 6 onwards) have not placed computational limitations but rather come with less printed documentation. This is similar to the difference between Mathematica's student and professional editions.

In releases prior to version 6, the student edition has had the following computational limitations:

• A maximum of 100 in floating point digits for computations and display.
• A maximum size of 8000 (in machine words or objects contained) for any algebraic object.
• A maximum of 3 dimensions for arrays.

Science kits, science lessons, science toys, maths toys, hobby kits, science games and books - these are some of many products that can help give your kid an edge in their science fair projects, and develop a tremendous interest in the study of science. When shopping for a science kit or other supplies, make sure that you carefully review the features and quality of the products. Compare prices by going to several online stores. Read product reviews online or refer to magazines.

Start by looking for your science kit review or science toy review. Compare prices but remember, Price \$ is not everything. Quality does matter.
