second derivative
Quick Summary
The second derivative is the derivative of the derivative of a function. In calculus, differentiation is the process of finding the instantaneous rate of change of a variable quantity. The first derivative of a function f(t) represents its rate of change, often interpreted as speed if f(t) is position. The second derivative, denoted f\u2033(t), is the derivative of the first derivative (f\u2032(t)). This second derivative often represents acceleration, which is crucial in understanding Newton's laws of motion. It is also used in graphing functions to determine concavity and identify local maxima or minima.123
