GRADE 11 UNIVERSITY MATH
Trigonometry Part 2 - Trig Angles
The goal of this unit is to introduce students to angles larger than 180 degrees and to work with their trigonometric ratio applications.
By the end of this unit, I will be able to:
- Determining coterminal angles (by adding and/or subtracting 360 degrees from initial angle) and determine principal angles (angles with same terminal arm between 0 degrees and 360 degrees)
- Use special triangles to determine the exact trigonometric ratios for angles of 30 degrees, 45 degrees and 60 degrees (and any related angles to these) without the use of a calculator
- Determine the exact trigonometric ratio of any angle, given a point on the terminal arm
- Solve for both angles between 0 degrees and 360 degrees with the same trigonometric ratio using the "rules" for the given trig ratio (cosine 360 - , sine 180 - , tan 180 + )
