Tina the ballerina
Storyboard Text
- That is still too high try going down some more.
- This is Tina, Tina is a beginner ballerina. Tina just started this new ballet class and noticed how her posture was different from everybody else. Tina was 10" away from the mirror and noticed she was holding her leg up at a 45 degree angle. She wonders how higher her leg has to go, so she uses math to try and help her posture get better. She finds out sin(45) x 10= 7.07. She has to raise her leg 7" higher.
- Tina showed her instructor her new posture and the instructor told Tina she needed to bring her leg down some more. She decided to try something new and she put her hand 7" away from each other on the rail and raised her leg to an 30 degree angle. She needed to know how much lower she had to keep her leg to keep a perfect posture. She knew that sin(30) x 7=3.5. So she has to raise her leg 4 more inches.
