This app is extremely powerful; it solves many graphing needs and calculations, and all this on the fly, on the shop floor, during some down time, when one has some ideas, or in meetings.
This is a killer app for mathematicians and physicists; financial calculations can also be compared with this app.
One just needs to know how to come up with equations and then one can compare:
-the equations/functions with graphing mode
-the equations/functions with some tweaks in graphing mode
-what if scenarios
-profitability
-values of ideas and concepts
One can solve for missing variables, do linear algebra, and do full calculus.
The equations are the rules of the game, these equations can be compared in graphing mode very easily.
