Some Common Maple Error Messages

Plotting

The constant 3.1415... is represented by Pi rather than pi.

Maple is case sensitive - X is different from x.

Multiplication is denoted by a *. Below xy is a single new variable whose name has two letters in it.

Two ranges are needed for a 3D plot.

Curves in 3 dimensions are plotted with spacecurve rather than plot3d. (The option thickness = 3 helps a lot with these pictures ...)

Omitting the view option often makes a picture much worse.

The same picture with the view option.

The same picture with the view option. and the style patchcontour.

Loading Files

Is the file transform_plots really in the subfolder library of the subfolder lcal of the Maple folder ?

Or has someone used apostrophes (') rather than backquotes (`) to specify the path. (The command paste pathname under the edit menu is the easy way to generate a correct path.)

The first step (Pacific above) is the top-level folder where the path starts, usually the machine name. When moved to a machine with a different name, the path won't work. So check if the machine name is correct.

Interface

Linear Algebra

The linear algebra package needs to be loaded.

Better:

Linear algebra operations need to be wrapped inside evalm to be computed.

Better:

Scalar Multiplication uses * rather than &*
