At this point, I don't have time to modify that tutorial, but to calculate a mathematical function: 0. click the mathematical function button 1. select the variable on the left 2. click the corresponding ">>" button which will place the variable in one of the function entries 3. select the second variable on the left 4. click the corresonding other ">>" button 5. select the add to plot check box 6. plot result
I don't have it in front of me, but the order of selecting the mathematical function should be able to be changed. You can "unselect" the ones on the left (using CTRL-click) to make sure they're not plotted if you don't want them. Let me know if that works for you.
