Solving a Trig Question: Identifying Independent & Dependent Variables

[WillyTech]

Here is a trig question that I've been thinking about. I want to know which one would be the independent and the independent of the points

(r , theta)

 

[chroot]

1) r and theta are not points, they are variables.

2) There is "dependency" in pure math. Neither variable can be said to be dependent upon the other. Even if you wrote down a function of these two variables, you could, in general, solve the equation for either variable.

3) Dependencies occur in measurements, where you change one variable (the independent variable) and observe changes in the other (the dependent variable).
