# Algebra Coach

The Algebra Coach is a program that explains algebra step-by-step exactly the way the teacher does. It is sophisticated but still easy to understand and use.

Download the Algebra Coach and try it free for three weeks. If you like it then you can buy it for \$24.95 – a fraction of the price of an algebra textbook.  And it comes with an electronic textbook! You can't get better value.

The picture below shows how the Algebra Coach works. Suppose that you are learning how to complete the square and that you are asked to put the quadratic expression x2 + 6 x + 16 into completed-square form.

1. You type the expression into the Listbox.

2. You click ‘OK’.

3. The Algebra Coach displays a set of buttons that operate on expressions.

4. You click on the ‘Complete the square’ button.

5. The Algebra Coach explains the completing-the-square process step-by-step,

6. ... and displays the result. The Algebra Coach can also teach you how to solve an equation. Click here to see how.

The Algebra Coach can also teach you how to prove a trigonometric identity. Click here to see details on that.

The Algebra Coach can solve every type of equation that you will encounter in high school or college algebra. Here is a (particularly nasty looking) rational equation. This equation requires about 20 steps to arrive at the solution and in step-by-step mode you would see all 20 of them. In result-only mode you see the result only. In exact mode the solution is shown as fractions. In floating point mode it would be shown as decimal numbers. What you have seen is just the tip of the iceberg. The Algebra Coach can do much, much more. To get you going the download includes:

• The Algebra Coach program.
• The Algebra Help e-book.
• A program help file showing how to use every feature of the Algebra Coach program; for example how to enter fractions, exponents and functions and how to set the options.  The help file also contains a quick start section – a good place to get started!
• Two sample files; one of which shows off the Algebra Coach's newest feature: the ability to prove trigonometric identities.
