Once I was in my calculus class and I had to demonstrate an optimization problem on the board. It was finding the maximum area of a triangle inside a circle with radius r. When I got to the part where I had to differentiate, I said something along the lines of, "the derivative of r*t with respect to t is r, because r is a constant." But when I think about it, r is not a constant, because it is a variable!
So now I am really confused about whether something is a constant or not. Am I correct in saying that r is a constant?
(Sorry if this is in the wrong forum. Even though I used an example from calculus, I'm not sure if this is entirely a calculus topic so I put it in the general section.)
