WolframAlpha Examples part 2 Presentation Transcript

  • 1. The examples here show you how to use WolframAlpha for checking your work and exploring other examples.
    For some topics other calculators and applets are also suggested to help you further.
    Examples Part 2
  • 2. Algebra – equations – unknown both sides
    Choose ‘show steps’
    See this post for further online equations resources
  • 3. Inequalities
  • 4. Inequalities
    See these resources for graphing inequalities
  • 5. Change the subject of a formula
    Note that sometimes showing the steps can cause confusion, here all that is required for example is to subtract c from both sides – then write the result the other way round!
    This does provide a very useful check though.
  • 6. Change the subject of a formula – example 2
  • 7. Change the subject of a formula – example 3
  • 8. Substitution
  • 9. Substitution – example 2
  • 10. Graphs
    note, values for x specified
    See this post for online graphing tools.
  • 11. Simultaneous equations
  • 12. Factorisation
  • 13. Factorisation
  • 14. Polygons
  • 15. Circles
  • 16. Standard Form
  • 17. Units - conversion
  • 18. Units - conversion
