Plotting functions with two variables
The preceding section describes how to plot functions that use a single variable ( x). You also can
plot functions that use two variables. For example, the following function calculates a value of z
for various values of two variables ( x and y):
z = SIN(x)*COS(y)
Figure 17-15 shows a surface chart that plots the value of z for 21 x values ranging from 2 to 5 (in
0.15 increments) and for 21 y values ranging from –3 to 0 (also in 0.15 increments).
