In calculus, the differential represents a change in the linearization of a function. The total differential is its generalization for functions of multiple variables. In traditional approaches to calculus, differentials (e.g. dx, dy, dt, etc.) are interpreted as infinitesimals.
An important application of differential calculus is graphing a curve given its equation y = f (x). This involves, in particular, finding local maximum and minimum points on the graph, as well as changes in inflection (convex to concave, or vice versa).
In this section we will compute the differential for a function. We will give an application of differentials in this section. However, one of the more important uses of differentials will come in the next chapter and unfortunately we will not be able to discuss it until then.
The meaning of DIFFERENTIAL is of, relating to, or constituting a difference : distinguishing. How to use differential in a sentence.
A Differential Equation is an equation with a function and one or more of its derivatives: Example: an equation with the function y and its...
Differential (dy) vs. Derivative (dy/dx) A differential dy is a quantity — it tells you how much y changes for a given small change dx. A derivative dy/dx is a rate — it tells you the ratio of change in y to change in x at a point. The relationship is dy=dxdy⋅dx.
The differential is a set of gears, that transfers engine torque to the wheels. It takes power from the engine and delivers it, allowing each wheel to rotate at a different speed on turns.
Although differentials seem to be a fairly theoretical concept on their own, they are an essential foundation of more advanced, highly applicable topics, such as calculus and differential equations.
