Interdependent variables have a fixed relationship i.e. given by some equation which can be solved for any of it's variables.
When you have two interdependent variables, you can use two way binding on two "number" controls. Changing one changes the other. UI for parameter which can be defined in two different ways
What do you do when you have three?
When you change one, you need to pick which of the other two to hold constant. How can this be expressed with controls? Do you have any exemplary examples?
