Once you have saved harmonicosc to your current folder, execute discriminant(3,2,5) in the command window. What happens? Undefined function or variable 'discriminant' On what line of code is the nested subfunction actually used? What is the discriminant if you run harmonicosc 10,2,60)7 How many "outputs" occur if you occur if you run harmonicosc(10,2,60)? (Hint: look at the workspace.) Check
