This trigonometry video tutorial explains how to evaluate trigonometric functions of any angle such as acute angles or special angles. It shows you how to find and use reference angles and coterminal angles to accomplish such a task as well as converting between radians and degrees as needed. This video contains plenty of examples and practice problems.

Here is a list of topics:

1. SOHCAHTOA - Opposite, Adjacent, and Hypotenuse of a Right Triangle

2. Right Triangle Trigonometry Basics

3. Sine, Cosine and Tangent Ratio

4. Secant, Cosecant and Cotangent Trigonometric Functions

5. Exact Value of Six Trigonometric Functions

6. Quadrants 1 to 4 - Sign of Sin, Cos and Tan Trigonometric Functions

7. Special Right Triangles - 3-4-5 Triangle, 5-12-13 right triangle, 7-24-25 triangle, 8-15-17 triangle

8. Pythagorean Theorem - Finding the Missing Side of a Right Triangle

9. Angle of Elevation and Depression Word Problems

10. Solving Right Triangles - Missing Sides and Angles

11. Evaluating Trigonometric Functions Given Terminal Point

12. Converting Radians to Degrees

13. Converting Degrees to Radians

14. Coterminal Angles - Positive and Negative - Degrees and Radians

15. Reference Angles in Radians - Trigonometry

16. Evaluating Trignometric Functions of Any Angle Using Reference Angles

17. Radicals & Square Roots - Rationalizing The Denominator

18. Special Right Triangles - 30-60-90 Triangle and 45-45-90 Triangle

19. Reciprocal Identities - Sec, Csc, and Cot Trig Functions

20. Unit Circle Approach - Trigonometry

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
