1. Our concept is Trigonometry By: Gerardo Alcántara and Cristian Garcia

2.  We use it in astronomy, navigation, naval and aviation industries, oceanography, land surveying and in cartography( the creation of maps). We especially use it in something that everyone loves……. Music!!!!!!!!! Even though we hear it, computers cannot so they represent it as constituent sound waves. Also the curved surfaces of steel, stone and glass would also not be possible without Trig. And also Digital imaging!!!!!!!! Also next time you go and get a CAT scan or an MRI the sine and cosine functions have a practical application of Trigonometry.

3.  The thing that interested us the most in this was that we use trigonometry every single day without knowing we are using it. Like music. Who doesn’t listen to it. When you play it in your computer those sound waves that appear are used with trigonometry. And also when you use your GPS. And also when you use utensils. Knives, forks, and spoons would not be curved if it weren't for trigonometry.

4.  We learned that if it weren't for trigonometry, we wouldn’t have many of the things we have, like knives, music, GPS, etc.

5.  Yes we would like to learn many things, especially when Ms. Bakas is going to teach it to us because it is very interesting.
