Definition
The first derivative represents the rate at which a function is changing at any given point. It measures the slope of the tangent line to the graph of a function at that point.
The second derivative represents the rate at which the first derivative is changing. It helps determine whether a function is concave up or concave down.
Critical points are locations where either the first derivative equals zero or does not exist. They can indicate maximums, minimums, or inflection points on a graph.
Rate of change refers to how quickly one quantity changes with respect to another quantity. In calculus, it often involves finding derivatives to measure this rate accurately.
