Its an introduction to a chain Law Calculus Maths It explains how the derivatives of a composite function a function of a function work For example f(g(x))=f'(G(x))*g'(x) or in other words du/dx=du/dy*dy/dx where u is a function of y and y is a function of x

We look at differentiation from the point of view of geometry by approximating our function to a tangent line value at a point where the curve and the tangent will meet Differentiation is the way to describe behaviourof the function at a given interval whether it is decreasing increasing or neither

Its an introductory class for differentiation Even though its only an estimated 45 min class it covers the main concept of the theme called "Differentiation" Its target audience is High School students and College The subject has been chosen due to its popularity and pratical use It also allows students to have a quick look at the one of the aspects of calculus
