Math paper on either application of differentiation or the application of integration with two worked out examples

Math paper on either application of differentiation or the application of integration with two worked out examples. 500 words needed. Paper on application of differentiation or the application of integration. You should have two worked-out examples. For example, Maximize a profit function or Minimize a cost function or maximize a revenue function. These are applications of the derivative. Application of integration: find the average value of a function, find the volume of a solid of revolution, etc. You may choose other applications; it is up to you. I just stated some examples. In your project, first, you introduce the concept and describe it, then you will do the examples, that is, the application of the concept. Your paper should also have references.
