### Trigonometry Lesson Plans

###

- Angle
Sums - Examine the angles in a triangle, quadrilateral, pentagon,
hexagon, heptagon or octagon.
- Determining
Functions Using Regression - This activity allows students to look
for functions within a given set of data. After analyzing the data, students
should be able to determine what type of function best represents the
data.
- Discovering
Trigonometry- Frequently asked questions about Trig.
- Follow
That Graph - Help your students to follow that graph with ease. In
this lesson, students investigate, analyze, and discuss the effects of
parameter changes on a trigonometric function using a graphing calculator.
- Fractions
& Line Graphs - Students will be able to understand, represent, and
use numbers in a variety of equivalent forms.
- Mars
Orbit - Astronomers now know that the planets in our solar system
travel around the Sun in roughly circular orbits. However, people used
to believe that the Sun and other planets orbited the Earth.

- Seismic
Waves- This example is about seismic waves.
- SSA
Construction- In this activity students will use Geometer's Sketchpad,
Cabri Geometry or the TI-92 to construct the SSA Ambiguous Case to demonstrate
the possible number of triangles which can be constructed based on the
length of the third side.
- The
EUVE Orbit- The students will study the nature of a satellite's orbit
around the Earth.
- The Sine
Function- To familiarize the students with the concept of the sine
function by defining, by graphing, by computer generating, by using a
"shop created" blackboard sine wave generator, and by presenting examples
of natural phenomena which result in sine wave motion.
- Trigonometric
Functions- To define and demonstrate the six trigonometric functions.
- Trigonometric
Functions - My students will know how to find the sine, cosine, and
tangent of right triangles using the sides of the triangle.
- Trigonometry
for Solving Problems - This lesson offers a pair of puzzles to enforce
the skills of identifying equivalent trigonometric expressions. Additional
worksheets enhance students' abilities to appreciate and use trigonometry
as a tool in problem solving.
- Trigonometric
Graphing - Explore the amplitude, period, and phase shift by examining
the graphs of various trigonometric functions. Students can select values
to use within the function to explore the resulting changes in the graph.
