Hello, this will sound stupid but I can't grasp what exactly a rate of change is. I know it's the rate at which something is increasing or decreasing etc, but what does that mean? Does rate in this context mean like the speed of change? Like the rate of change of y with respect to x would be the speed of change of y relative to the change of x?
For some reason I just can't wrap my mind around it and I've been doing calc and derivatives all year. Any help in a more elaborate meaning would be helpful.
