Quick Introduction

For the most part we will be plotting in Maple. To get started, enter the following at the ;SPMgt; prompt:

      plot(sin(x), x=0..2*Pi);

To excute the command hit the Enter or Return key after you've typed the line. This will plot the function on the interval . Notice we write Pi for and we use * for multiplication.

Let us try a few things:

• Go back to the command you entered and change the interval to . Re-enter the command.
• Change to the function by changing the command to read

        plot(x*sin(x), x=0..2*Pi);

• Change to the function by changing the command to read

        plot(x^2*(sin(x)+1)^2, x=0..2*Pi);

• Change functions altogther to plot the exponential function .

        plot(exp(x), x=-2..2);

We can also use the plot command to plot several functions at the same time. Try this:

      plot({sin(x),cos(x)}, x=-2..2);

Notice the functions are separated by a comma and the list of functions is enclosed in braces.
