- Use the input function and a variable to collect and store data from a user
- Use the randint function to generate triangle side lengths
- Use the randint function to determine sine, cosine, or tangent prompts
- Use if..elif..else statements to make decisions
- Use the Pythagorean Theorem to find missing triangle side lengths
- Use right triangle trigonometry ratios to solve problems
About the Lesson
For this lesson, students will write a program that generates a random sine, cosine or tangent ratio. It will ask the user to enter a different trigonometric ratio based on the given triangle information. It will evaluate the user’s input. If the user’s input is incorrect, it will give the correct ratio.
Note: This lesson requires the use of TI-Nspire™ CX II technology with OS 5.2 and above.
