Graph Exercises Requirements

Feature:

Provide a welcome screen with “Graph Exercises” as title
Display equation (linear or sin function) and four possible solutions in the form of graphs
The graph exercises allow users to take quizzes on certain graphs (pick the corresponding graph)
Graphs and possible solution are generated at random using Python scripts
- To generate different graphs, the program must be able to edit variables
  - For linear equations y = mx + b, m and b must be editable
  - For sin functions y = A sin(b * theta + phi), A, b, and phi must be editable
    - Program must be able to edit any number of variables, not just one or all
After a session, results are returned to the user to show performance

User must have registered and created an account to do graph exercises
User must be logged into system in order to do graph exercises
Must have links on home page and other relevant locations on website directing users to the graph exercises

Once directed to the graph exercises, user is greeted by a welcome screen titled “Graph Exercises”; there are options to start a session or go elsewhere on the site
After entering a session, the user will see a page with an equation and four corresponding graphs
- That graphs each have a button to allow the user to select the one they believe to be correct
After they select an answer they see:
- The correct graph highlighted in green
- If they selected the incorrect answer, their selection highlighted red
- Text telling either telling them “Correct!” or “Incorrect”
- A button titled “Next” to advance to the next graph exercise
When a user completes a graph exercise session:
- A string that says how many questions our of how many attempts they got correct
  - A percentage representation of this number (perhaps incorporating prior results once the data tracking functionality is finalized
- Try again link that takes the user back to the welcome screen for graph exercises
