# Manual An Introduction to Mathematica

That result, if achieved, would make the development of new programs simpler, faster, and less expensive. In that more ideal world, scientific research could see significant improvements in data gathering, shortening the time required for projects. Businesses may well have the functional capability to accomplish research and development goals in far shorter periods, suggesting the costs of everything from small appliances to advanced weapons systems would be reduced. There are practical applications where everyday activities would benefit as well as large organizations.

When the idea is to simplify the ways devices operate, the applications are nearly endless.

Even devices like smartphones could be simplified to make their operation easier and more intuitive. The internet of things, or the networking of numerous devices to make communication between those devices simple, is another good example. Appliances, security systems, and a wide variety of other devices, to be truly interconnected and functional, require a means to simplify that connectivity.

Wolfram Language may, indeed, provide a way for all types of devices to communicate effectively. While the long-term implications are still not fully understood, Wolfram clearly believes in possibilities designers have not yet begun to explore. In reality, the potential uses for the Wolfram Language are almost unlimited in terms of our current understanding. Take, for example, the current use of drones. While drones today generally require some level of human interaction to function, fully autonomous drones could accomplish more. The tutorial accompanies the textbook Applied Differential Equations. Therefore, the primary goal of this document is not to explain the material in the text; rather, it is to give you the tools to solve problems and to present the capabilities of available software packages as they are needed by someone studying the text. This tutorial is designed for students who have absolutely no prior experience with computer algebra systems and programming , which reflects the pace, tone, and content of the material presented.

Because there are many ways to solve physics problems, we present a variety of styles to illustrate different ways of solving similar problems using Mathematica. We emphasize that the solutions presented here are not necessarily the most efficient for dealing with all possible instances.

Introduction to Mathematica

While we do discuss writing efficient Mathematica code, we sometimes sacrifice the most elegant or efficient solution in favor of one that is most easily understood pedagogically. As a result, this tutorial will sometimes introduce several different ways to do the same thing. It is always good to be aware of these alternate pathways, but you are welcome to pick whatever notation you like the best.

A solution of a realistic problem is often hampered because the algebra is too complex for anyone but the dedicated researcher. Just as the calculator eliminated laborious numerical computations, symbolic software programs eliminate arduous algebraic computations. While computer power is no substitute for thinking, it spares the scientist from performing mundane mathematical steps, and thereby frees time for creative thinking.

This tutorial can be used to introduce students who are taking the first course in differential equations at Brown University, it is APMA , Methods of Applied Mathematics - I to a symbolic mathematical computation program Mathematica that was conceived by a theoretical physicist Stephen Wolfram born in in London, England in late 's. Mathematica is a great computer algebra system to use, especially if you are in applied areas where it is necessary to solve differential equations and other complicated problems.

It was created by a brilliant entrepreneur, who was inspired by Maxima , the first computer algebra system in the world, and produced an elegant, coherent, and extremely general approach to computing. Mathematica provides friendly tools to solve and plot solutions to differential equations, but it is certainly not a panacea of all problems. This computer algebra system has tremendous plotting capabilities.

It is backed by highly extensible Python code, relying on SymPy for most mathematical tasks.

This tutorial contains many Mathematica scripts. You, as the user, are free to use all codes for your needs, and have the right to distribute this tutorial and refer to this tutorial as long as it is accredited appropriately. The attempt to solve physical problems led gradually to mathematical models involving an equation in which a function and its derivatives play important roles.

However, the theoretical development of this new branch of mathematicsOrdinary Differential Equationshas its origins rooted in a small number of mathematical problems. These problems and their solutions led to an independent discipline with the solution of such equations an end in itself. According to some historians of mathematics, the study of differential equations began in , when Gottfried Wilhelm von Leibniz wrote the equation:. Only in special cases can a particular differential equation be integrable in a finite form, i.

5. In the general case one must depend upon solutions expressed in infinite series in which the coefficients are determined by recurrence-formulae. Mathematica is based on its own programming language, called Wolfram language. Unlike other programming languages, the philosophy of the Wolfram Language is to build as much knowledge about algorithms and about the world into the language as possible. There is nothing that can be done in Mathematica and absolutely can not be done in other programming environments.

### What you will make

The point is that many things are done in Mathematica with less or a lot less effort and time, because a lot of both generic and specific functionality is already built in Mathematica. And because it is so general, this statement is expected to be true for almost any field where some computations, prototype or program design and development, simulations etc are used. Mathematica is split into two parts, the kernel and the front end.

The kernel interprets expressions Wolfram Language code and actually does the computation and returns result expressions. Mathematica is the most widely used system for doing mathematical calculations by computer, including symbolic and numeric calculations and graphics. It is used in physics and other branches of science, in mathematics, education and many other areas.
