WolframAlpha Examples part 3

  1. 1. The examples here show you how to use WolframAlpha for checking your work and exploring other examples. Note that step by step solutions are for subscribers only but WolframAlpha is free to use for an unlimited number of queries every day so it is great for checking answers or generating lots of examples. Examples Part 3
  2. 2. Graphs – check the intercept on the y axis
  3. 3. Graphs – check the intercept on the y axis
  4. 4. Graphs – check the gradient (slope)
  5. 5. Graphs – check the gradient (slope)
  6. 6. Coordinates
  7. 7. Graphs – cubic functions
  8. 8. Graphs – reciprocal functions
  9. 9. Graphs – power functions
  10. 10. Graphs – power functions
  11. 11. Factorising Quadratic Expressions
  12. 12. Completing the Square Note, we see that the minimum value of this function is 1 which happens when x= -3. You should be able to see why this is the case from the completed square form. See next slide also.
  13. 13. Minimum value of a quadratic
  14. 14. Solving Quadratic Equations
  15. 15. Solving Simultaneous Equations
  16. 16. Algebraic Fractions
