Trigonometry

By: Justin Ferranto


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.


Where did Trig. originate?

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


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.


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.


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-


Interesting trig. website
