Nov 16, 2022 · 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 …

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 …

We now take a look at how to use differentials to approximate the change in the value of the function that results from a small change in the value of the input.

Learn differential calculus—limits, continuity, derivatives, and derivative applications.

To discuss this more formally, we define a related concept: differentials. Differentials provide us with a way of estimating the amount a function changes as a result of a small change in input values.

The intuitive idea behind differentials is to consider the small quantities “ d y ” and “ d x ” separately, with the derivative d y d x denoting their relative rate of change.

This arises from the Leibniz interpretation of a derivative as a ratio of “in finitesimal” quantities; differentials are sort of like infinitely small quantities. Working with differentials is much more effective …

Differentials are, essentially, very small changes in input or output of a function. In calculus, they are typically considered to be infinitesimals (infinitely small in value).

Example 2: Use differentials to approximate the change in the area of a square if the length of its side increases from 6 cm to 6.23 cm. Let x = length of the side of the square.
