Advanced math/trig

By: Chelsie Pinckney

what is trigonometry
What is Trigonometry
  • Study of how sides and angles of a triangle are related to each other
when where did trigonometry originate
When/where did trigonometry originate
  • It came from the ancient Egyptian and Babylonian
  • It was kind of a mathematic way to work with triangles
3 most used trig functions and their ratios
3 most used trig functions and their ratios
  • Sine: a/h (opposite over hypotenuse)
  • Cosine: b/h (adjacent over hypotenuse)
  • Tangent: a/b (opposite over adjacent)
  • Cotangent, secant, and cosecant are three other functions
three other functions
Three other functions
  • Cotangent, secant, and cosecant
  • All of the functions require being set up as a ratio
  • Cosine, cotangent, and cosecant use horizontal lines
  • Secant, sine, and tangent use vertical lines
  • I have seen sine tangent and cosine on the calculator we use in class.
real world applications that involve trig
Real-world applications that involve trig
  • Building bridges and determining the force of a beam
  • Whether your ladder is long enough to clean out a gutter
  • Creating a map (cartography)
  • Digital imaging
unit c ircle
Unit Circle
  • A circle with a radius of one
  • Demonstrates that sine and cosine are periodic functions
  • Yes circles and triangles
discovery of trigonometry
Discovery of Trigonometry
  • BartholemaeusPitiscus
  • August 24, 1561 – July 2, 1613
  • Studied theology in Zerbst and Heidelberg

project idea
Project Idea!!!
  • Football players use trigonometry when tackling a player
  • I could go to a football game or practice and figure out the best tackling angles.
