LiveMath Internet allows web browsers to display interactive mathematical LiveMath notebooks. Each notebook is a white rectangle on a gray web page, so you can easily identify the LiveMath samples.

Some notebooks have a simple graph that you can play with, while others have multiple complex graphs, expressions, and equations you can modify.

Visualizing with Graphs

By clicking on different parts of a graph, you can rotate the graph to see it at different angles. Below are examples of a 2D graph and a 3D graph. Point your mouse in the middle of either graph and click and drag your mouse sideways and up and down for different views.

The buttons on the right side of the graph, if displayed, let you zoom in or out. To zoom in, choose the Knife tool and draw a rectangle over the section you want to see more closely. To zoom out, click on the Rocket.

The buttons with grids change the resolution of the curve. For surfaces in 3-space, you can change the number of panels used to approximate the surface.

Animated graphs appear to move as MathView cycles through the given range of values. Click on the middle of the graph to start or stop the animation.

The first time LiveMath cycles through all the frames, it saves them in memory, so it may take a little longer to view. After the first cycle, it should speed up. If there is a number in the upper left corner, it identifies the frame number in the cycle.

Modifying Equations

One of the most interesting things you can do with MathView Internet is to modify the equations in a notebook and view the results.

In the notebook below, use the mouse to highlight/select the number 2, and then type in a different number. The resulting graph will be different from the previous one, since it is linked to the equation.

To change a number

just click or select over it and type in a new number. You can double click to select the whole number.

In the commands below, you can replace x by any number or expression, so instead of adding x, for example, you could add 5 or add x + 6.

To add the variable x

select what you want to add it to and type + x

To negate an expression

select what you want to negate and type -

To subtract the variable x

select what you want to subtract it from and type + - x

To multiply by the variable x

select what you want to multiply it to and type * x

To divide something by the variable x

select what you want to divide and type / x

To delete an expression

select what you want to delete and press your delete or backspace key. If you get a question mark ?, press the delete key again.

To type in the function sin(x)

just type in sin(x) The functions available to you are restricted to those the notebook author declared.

To type in the constants like pi or e

just type in e for e

type in 'p for pi

type in 'N for infinity.

If your notebook becomes hard to read, just click on the Reload button and your notebook will be restored to its original form.
