Expressions

$\blacktriangleright$ To make a cylindrical plot of an expression

1.
Enter the expression in your document.

2.
With the insertion point in the expression, from the Plot 3D submenu choose Cylindrical.


The following example shows a plot of the cylinder r = 1 obtained as the 3D cylindrical plot of the expression 1, with 0≤θ≤2π, and z≤1.

You can plot more than one expression at once by separating the expressions with a (red) comma. The following example shows a plot of the cylinders r = 1 and r = 1 - z obtained as the 3D cylindrical plot of the expressions 1 and - z, with 0≤θ≤2π, and 0≤z≤1. To get this plot, either plot both expressions together (as indicated), or drag one of the expressions onto a plot of the other.
