@adamscochran I agree with your take, but it's funny coming from someone with "Professor" in their bio when they are an adjunct at a scammy community college/diploma mill, and has an online MBA degree.
@reflexerfinance Derivative: Like anticipating road changes. Approaching uphill? Press gas to maintain speed. Nearing crest? Ease off to avoid overspeeding. It's preemptive action based on rate of change.
@reflexerfinance Integral:Imagine you're driving on an incline. You notice you've been consistently under the speed limit for a while. The integral part is like pressing the gas pedal a bit more to compensate for this persistent error, even if the proportional part isn't calling for much change.
