  1. Trigonometry Project • By: Brittany Easter Thursday:

  2. What is Trigonometry? • Trigonometry- a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides.

  3. When/where did trig originate? • Ancient Greece • Hipparchus • Angles = 360 degrees • Cosine and Sine

  4. Ex. 1: • Trigonometry is commonly used in finding the height of towers and mountains.

  5. Ex. 2: • It is used in finding the distance between celestial bodies

  7. Ex. 4:

  8. Three Most Used Trig Functions and Their Ratios: • Sine: opposite/hypotenuse • Cosine: adjacent/hypotenuse • Tangent: opposite/adjacent

  9. Interesting Website(s): • http://www.mathsisfun.com/geometry/unit-circle.html

  10. Trig Project Idea: • Create a “Math Help” web site (must be educational and appropriate, possible use in the future by your instructor is ideal and desired, videos, interactive applets, etc suggested)* • My idea for this is that we create a website that students can go to and use for future homework help on math problems. The website doesn't have to be all about trigonometry help, it can be about other math problems, but I thought it would be neat if everyone participated in creating a website for this.

  11. The Unit Circle: • What is it • A unit circle is a circle with a radius of one. • How and why is it used in trigonometry? • The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here. • Are circles and triangles related? • In a way, yes. http://www.youtube.com/watch?v=ao4EJzNWmK8&feature=colike
