Trig Identities and Proofs Worksheet
I use this worksheet in my Pre-Calculus classes to study (as a whole class) for the Trig Proof quiz. In my class, this activity is called "Check Yo' Skills." Students need to
-Write the trig expression as the sine, cosine, or tangent of an angle
-Simplify the trig expression to a single term
-Prove the trigonometric identity
-Find the exact value of each trig expression using a sum or difference identity
-Find all solutions in the interval zero to 2*pi without using a calculator bu giving exact

Unit Circle Exploration
This is an activity to help students visually understand the patterns in the Unit Circle. They will cut out special right triangles and place these on a handout with pictures of the Unit Circle to help them find the missing angles and coordinates. Students will have a deeper understanding of patterns in the Unit Circle, which will help them remember it.

Graphs of Sine and Cosine
Students will match 10 graphs to 10 sine or cosine equations by finding the amplitude and period of each function. Students will then identify the amplitude and period of other sine and cosine functions, although they will not be required to graph.
Students can work as a group or by themselves. This is best used as a resource after students have learned how to find amplitude and period, and can also recognize the difference between sine and cosine graphs.

Modeling Tide Heights with Sine Functions Project
This is a project in which students do research on the heights of tides in different parts of the United States for different phases of the moon. Students will write the sine equations that best model these tides, and then graph their displays and answer questions pertaining to their functions and graphs. This project can be used as an in class assignment that is graded or just as an exploration activity. The grading rubric for the assignment is included.

PreCalculus Mathematics Formula Sheet
This is a formula sheet that I give to my students in Grade 11 Functions/PreCalculus.
Feel free to edit this sheet as you wish! I will usually review it at the beginning of each year to add or remove those formulas that may not be needed depending on the course I am teaching.
The formulas are given as such:
- Linear
- Quadratic
- Trig ratios, trig identities, sine and cosine law
- Arithmetic/Geometric sequences and series
- Compound interest and exponential growth and decay

PHET Vector Lab (Online Simulator)
I created this lab as an intro into two dimensional motion for my physics classes. The lab uses all the techniques of adding vectors head-to-tail and demonstrates for them that the two vectors being added to make a resultant are the components of that resultant. This lab is great practice and very self-explanatory for grades 11 and 12. I created this lab so that it was an electronic lab so that they could open the lab on their computers, fill out the lab in MS Word, and submit it back to me onli

Highly Effective Strategy for Teaching Right Triangles - FREEBIE!
Give students a transparent tool to help them label triangles!
Students often have trouble labeling parts (such as x, 2x, a, b, c, opposite, adjacent, hypotenuse, etc) of triangles for Special Triangles, Pythagorean Theorem, and Trigonometry. To help my students do this correctly, I give each student a labeled triangle printed on transparency film.
Then when students are working on one of these types of problems, they line up their transparency with the problem on their paper. They line up
