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 ...

High-throughput time-series data is increasingly available, yet estimating time-derivatives from such data can remain a challenge. Here, the authors provide a non-parametric method for inferring ...

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