4.3. Surface Plots

Genius can also plot surfaces. Select the Surface plot tab in the main notebook of the Create Plot window. Here you can specify a single expression which should use either x and y as real independent variables or z as a complex variable (where x is the real part of z and y is the imaginary part). For example to plot the modulus of the cosine function for complex parameters, you could enter |cos(z)|. This would be equivalent to |cos(x+1i*y)|. See Figure 4-5. For plotting using the command line see the documentation of the SurfacePlot function.
