Trigonometry Project
Thursday
• By Brittany Easter

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.

11
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.
