5.2 Graphing in Three Dimensions • 125To plot a cone in cylindrical coordinates, let r equal z and let θ varyfrom 0 to 2π.> cylinderplot( z, theta=0..2*Pi, z=0..1 );The cylinderplot command also accepts parametrized plots. Thesyntax is similar to that of parametrized plots in Cartesian (ordinary)coordinates. See this section, page 121.cylinderplot( [ r-expr, theta-expr, z-expr ],parameter1=range, parameter2=range )The following is a plot of r = st, θ = s, and z = cos(t 2 ).> cylinderplot( [s*t, s, cos(t^2)], s=0..Pi, t=-2..2 );Refining PlotsTo create a smoother or more precise plot, calculate more points. Use thegrid optiongrid=[m, n]where m is the number of points for the first coordinate, and n is thenumber of points for the second coordinate.
