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

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

Proof of cos(A-B)=cosAcosB+sinAsinB Sum & Difference Identities for Power Point
Included in this zip folder are 4 Power Point files. 1 is the proof, 1 is an assignment and 2 are student 1 page printables. A brief description of each:
The proof is a 32 slide file. The identity cos(A-B)=cosAcosB+sinAsinB is proved. The distance formula is used to derive this identity based on a rotated angle in the unit circle. The student must previously know:
1. The definition of sine
2. The definition of cosine
3. The Pythagorean Identities
4. Expand a binomial
