Modelling and Change: In-Depth Investigation of Two Functions

This document provides an in-depth investigation of two functions in Modelling and Change. It explores the use of tangent lines, tangent planes and Taylor polynomials for approximate integration. The document also discusses the importance of the area under the tangent line and the use of polynomial approximations of two-variable functions as a method of approximating integration of two-variable functions. It includes solved assignments, essays, dissertations and more.
