- Problem Statement
- I have been given a generic question, however I don't know how to interpret it if the variables had an assigned meaning.

- Relevant Equations
- f'(x) = ##\frac{d}{dx}## (##\int## ##\frac{1-t^2}{1+t^2}## *dt). The integral has the limits 0-x.

I am able to solve the problem however if x was position and t was time how is this problem interpreted?

I know, for example that ##\frac{dx}{dt}## tells us how the position of something changes as time changes (or instantaneous change) and an integral gives a net change so to speak.
