2.  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.  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-
