## 课程大纲

What’s the connection between the size of a city and the number of gas stations in it? How would you describe this relationship? How would you try to visualise and understand it? Study real-world connections using algebra and geometry In this free online course, we’ll look at a wide spectrum of interesting, and often surprising, mathematical relationships in our everyday world. These real-world interconnections can be studied using algebra and visualised concretely using graph paper and pencil, along with modern technologies such as graphing calculators and interactive graphing software. Algebraic functions and their graphs allow us to make predictions, evaluate actions and test theories about many things - such as the trajectory of a football, the number of times the word “of”’ appears in a novel, scaling laws in biology and the relationship between supply and demand in economics. Explore linear, quadratic, inverse and power relationships Our journey begins with the fundamental idea of direct proportionality. In Week, 1 you’ll meet lots of examples of linear relationships in the world around us. You’ll learn to represent these relationships algebraically and graph them geometrically in the Cartesian plane to aid in visualisation. In subsequent weeks, we’ll look at quadratic relations from Apollonius to Bezier; inverse relations and the associated geometry of hyperbolas; and finally power relationships, higher degree polynomials and rational functions. We’ll discuss the history, look at lots of examples, and show you how to solve an interesting variety of concrete problems. Gain valuable skills for further study Understanding basic mathematical relationships is vital to many fields of study: biology, engineering, business, economics, political science and design. By the end of this course, you’ll have hands-on experience with a wide range of explicit examples, be familiar with a core area of pre-calculus mathematics, and be ready to go on to more advanced study of calculus or linear algebra. Whether you’re encountering these topics for the first time or brushing up on your high school mathematics, we hope you’ll actively join our community on this journey through some fascinating and practical topics that have contributed much to our understanding of the world around us.

## 平台

FutureLearn est une plate-forme d'apprentissage proposant des formations en ligne ouvertes à tous (MOOC)

Fondée en Décembre 2012, la société est entièrement détenue par l'Open University à Milton Keynes, en Angleterre.

Elle est la 1ère plateforme offrant des MOOC au Royaume-Uni, avec à son actif plus d'une cinquantaine d'universités partenaires provenant du Royaume Uni mais aussi du reste du monde.

FutureLearn se différencie également par des partenariats avec des entités non-universitaires comme le British Museum, le British Council, la British Library et la national Film and Television School.
