By using a derivative, you can take a supply function and determine the marginal revenue at any given quantity of product.

As the name implies, the derivimeter finds the derivative of a function. To do that, you have to plot the function on a piece of paper that the meter can measure.

What is the derivative and why do you need it in physics? Here is a very quick introduction to derivatives to get you through your first physics course.

Lagrange interpolation estimates a function at a reference position x from known values of the function at distinct non-uniformly spaced points x1, ....., xn. Here, the corresponding η-point ...
