Показать описание
Precalculus section 4.3 Right Angle Trigonometry
This section will cover the following objectives:
- Use right angles to evaluate trigonometric functions
- Find function values for 30, 45, and 60 degree angles
- Use equal cofunction identities
- Use right angle trigonometry to solve applied problems
Also, at about 22 minutes, I construct the full unit circle
