Derivative as a rate of change
WebThe derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of … WebFor this reason, the derivative is often described as the "instantaneous rate of change", the ratio of the instantaneous change in the dependent variable to that of the independent variable. Derivatives can be generalized to functions of several real variables.

WebThe rate of change of a function of several variables in the direction u is called the directional derivative in the direction u. Here u is assumed to be a unit vector. Assuming w=f(x,y,z) and u=, we have Hence, the directional derivative is the dot product of the gradient and the vector u. Note that if u is a unit vector in the x ... WebNov 16, 2024 · The rate of change of f (x,y) f ( x, y) in the direction of the unit vector →u = a,b u → = a, b is called the directional derivative and is denoted by D→u f (x,y) D u → f ( x, y). The definition of the directional derivative is, D→u f (x,y) = lim h→0 f (x +ah,y +bh)−f (x,y) h D u → f ( x, y) = lim h → 0 f ( x + a h, y + b h) − f ( x, y) h
