The most significant thing I learned in this class is that Triangles are more than just a shape. They contribute to a lot of real-world calculations. The most common application would be calculating distance to objects, height of objects, or how far apart objects are. Trigonometry also plays a major role in Physics. Trigonometry is used to calculate waves of sound, light, and others that emit a sine or cosine wave. It can also be used to calculate trajectory, vectors and scalers. Knowing how to use Trigonometry, I have already begun to use it as a tool in my life. At work, I was tasked with setting up a projector with specific criteria. The projector had to display onto a wall in which someone who is 6 foot tall or less wouldn’t be blinded by the projector if they were to walk in front of the projection being at least 2 feet away from the wall. The other restriction was that it had to display at least 120 foot diagonal display on the wall. I used the skills I learned in Trigonometry to calculate how high the projector needed to be, how close to the wall it had to be, and the angel at which the light projected from the unit. Needless to say, I was able to come up with the perfect solution for this very easily and very much impressed my supervisors. All this considered, I believe Trigonometry to be a very useful tool that I will carry with me for the rest of my life.
