# Brief Maple Support Notes

## Sources

There many sample worksheets in the Local subfolder of the Maple folder on each Macintosh. There are additional course related materials in other folders including the Math 222 one which covers multivariable calculus related topics, and Math 221 on linear algebra.

## Keystrokes

• Maple is case-sensitive - capitalization counts !
• The transcendental number e=2.71... is denoted by E.
• The area of a unit circle is Pi, not pi.
• The square root of -1 is I, not i.
• By default on Macs in the lab, use ENTER rather than RETURN to evaluate everything associated with the current prompt.
• Lines always end with semi-colons or colons.

## Plotting Functions

• 3D Plotting Examples and 2D Plotting Examples.
• Load the plots package first (with(plots);!
• Use plot3d for plotting explicit two variable functions (z=f(x,y)...) or parametric surfaces.
• Use spacecurve for plotting curves in R^3.
• Use plot for plotting one variable functions and parametric curves.
• For surfaces f(x,y,z)=0, use implicitplot3d.
• For curves f(x,y)=0, use implicitplot.
