This new theory dispenses with the usual complicated circular functions cos and sin and tan and their many complicated relations and establishes a trigonometry based entirely on elementary arithmetic and algebra. The [course_title] will provide an overview of Rational Trigonometry and how it allows us to reformulate spherical and elliptic geometries, hyperbolic geometry, and inversive geometry, and leads to the new theory of chronogeometry, along with many practical applications.
Assessment
This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.
