Patrick Jones on the Law of Sines – Example 1

In a previous post (a video tutorial on the properties of logarithms), I introduced you to the wonderful math tutorial videos by Patrick Jones. In the following video, Patrick introduces the law of sines (from trigonometry) and gives an example to show how you might use this mathematical relationship between the length of the sides and the sines of the angles of a triangle. Enjoy!
