How To Differentiate By First Principles вђ Mathsathome To differentiate any exponential function, differentiate the power and multiply this by the original function. this can be written mathematically as when , . alternatively, this can be written as when , . for example, differentiate f (x) = e 3x. u is the power of the exponential, which is 3x. u’ is the derivative of u. This video teaches how to solve calculus differentiation problems with the use of the first principle method.watch to learn the second method of differentiat. In this a level maths video i show you how to differentiate from first principles. it's quite simple once you know how! time stamps: 0:00 intro 0:14 what is. The derivative from first principles. in this section, we will differentiate a function from "first principles". this means we will start from scratch and use algebra to find a general expression for the slope of a curve, at any value x. first principles is also known as "delta method", since many texts use Δ x (for "change in x) and Δ y (for.
