Web3. Rate of Change. To work out how fast (called the rate of change) we divide by Δx: Δy Δx = f (x + Δx) − f (x) Δx. 4. Reduce Δx close to 0. We can't let Δx become 0 (because that would be dividing by 0), but we can make it head towards zero and call it "dx": Δx dx. You can also think of "dx" as being infinitesimal, or infinitely small.
