Nettet4. jul. 2024 · 1 Answer. It just means the 'rate' of something in an instant in time. It is usually found as the limit of some function that takes the difference between to 'rates' or points or whatever over decreasing increments of time. It can often be found by taking the first of second differential of some function. NettetThe rate of change at any given point is called the instantaneous rate of change. This can be calculated from non-linear relationships by drawing a tangent to a curve and …
