Explorations with Coding: Trig Ratios: Gettin' Trig-y with Python

Objectives

• 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.
