**Plotting two-variable mathematical functions**

Figure 140-2:
Using a 3-D surface chart to plot a function with two variables.

As long as the x and y values have equal increments, you can specify any two-variable formula

you like. You might need to adjust the starting values and increment values for the x and y

variables. For a smoother plot, use more x and y values with a smaller increment.

Here are some other formulas you can try:

=SIN(SQRT($A2^2 + B$1^2))

=SIN($A2)*COS($A2* B$1)

=COS($A2* B$1)
