Instructional Ideas

  • Use a graphing program to graph several members of the family of solutions
  • Provide opportunities for pupils to verify solutions of an equation
Classroom Considerations

  • The class should know how to differentiate a function
Pros

  • Uses a graphical representation of the particular solution
  • After making a mistake, the presenter talks through the process to find his mistake — great for pupils to see
Cons

  • None
