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

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.

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.
