The first of the Trigonometric Trilogy! In this week's video we take a look at a clever way of using Autograph to practice working out the length of missing sides using Trigonometry (sin, cos and tan) and Pythagoras. We begin by constructing a right-angled triangle, and then use a sneaky technique to cover up a measurement. The finished article can then be used in class or at home for infinite trigonometry practice! More on this next week!
