Question

How do I find instantaneous velocity on a calculator?

Answer 1

First, type in your position function. I will use `f(x)=x^2-3x` as an example here. Here are the exact key strokes:

Let us find the instantaneous velocity at `x=4`.

Hence, the instantaneous velocity at `x=5` is `5` (at the bottom of the screen).
