  1. Trigonometry By: Justin Ferranto

  2. What is Trigonometry? • Trig. Basically deals with the study of triangles. • Mathematicians use trig. to study relationships between the sides and angles of a triangle.

  3. Where did Trig. originate? • Trig. is believed to have originated from the Greek words “trigonon” and “metron” which mean triangle and measure.

  4. Mathematician who founded trigonometry • The main mathematician who invented trig was Hipparchus. • Hipparchus was born at Nicaea in Bithynia and was believed to be the main mathematician who invented trig.

  5. Four real-world applications that involve trig. • It’s used to find the distance between stars and other things in space • Used in oceanography to calculate thetheight of the tides. • Used to find the height of towers and mountains. • Architects use it to determine structural load, roof slopes, ground surfaces, etc.

  6. Trig functions The six trig functions are sine, cosine, tangent, Secant, Cosecant, and Cotangent. Three most used: sine, cosine, and tangent. Sine- Tangent- Cosecant- Cosine- Secant- Cotangent-

  7. Interesting trig. website • http://www.mathsisfun.com/algebra/trigonometry.html • Basically gives an introduction to trigonometry.

  8. A fun trigonometric project. • G:\Trigonometry Project Information Sheet.doc

  9. What is the unit circle? • The unit circle is just a circle with a radius of one.
