Non-right angled trigonometry
Here we take trigonometry to the next level by working with triangles that do not have a right angle. We will work on three key rules. The Sine rule, the Cosine rule and the formula for th area of a triangle. All of these involve linking four bits of information about a given triangle. When you know three of them you can figure out the fourth. These problems are then extended in to three dimensions. Key Concepts In...
