Definition: Taylorism is a philosophical and mathematical approach that emphasizes the use of derivatives in analysis. It was developed by the French mathematician, Joseph Louis Lagrange, in the early 18th century, and it is based on the concept that certain functions can be approximated or "taylorified" to give an idea of their behavior at a given point. The key ideas behind Taylorism are: - The use of derivatives: Derivatives allow us to find the slope of a function at
