Instructional Ideas
- Provide the video to pupils struggling with finding limits of trigonometric functions
Classroom Considerations
- Learners should already know the limit as x approaches 0 of basic trigonometric functions and of (sin x)/x
- Scholars need to be able to apply properties of limits
- This video is hosted on YouTube
Pros
- Thoroughly explains all steps taken
Cons
- Narrator speaks at fast pace
- For a video that purports to teach everything about limits of trig functions, it only covers one example
