Trigonometric Functions

Welcome to the Trigonometric Functions guide at TV Tome. Trigonometric Functions is the second component of the TVO Concepts in Mathematics project. Its plot is an extension of the adventures of Ed and Charlie, who had graced the 1987 production Vectors. Season 1, subtitled Solving Triangles, finds Ed and Charlie on a space probe to the center of the galaxy. Along the way, they encounter unusual problems that require using not just trig ratios, but also the sine law and the cosine law. Individual programs are set up for each. Season 2, subtitled Sinusoidal Waves, is a bit more distorted. Ed and Charlie find themselves in another dimension and can't seem to get back their familiar world. This season goes far beyond triangles and straight lines. There is no editor for this show. If you would like to be the editor look here for details.
