(All Steps) Use Newton's divided differences set out in tabular form as in notes to find a quadratic approximation for e^x using x=0,1,2, and use this to


Question: Use Newton's divided differences set out in tabular form as in notes to

  1. find a quadratic approximation for \(\mathrm{e}^{\mathrm{x}}\) using \(\mathrm{x}=0,1,2\), and use this to find an approximation for \(\mathrm{e}^{\mathrm{x}}\) at \(\mathrm{x}=1.5\)
  2. extend this approximation to a cubic using \(\mathrm{x}=3\), and use this to find an approximation for \(\mathrm{e}^{\mathrm{x}}\) at \(\mathrm{x}=1.5\)
  3. compare the above approximations with the value of \(\mathrm{e}^{\mathrm{x}}\) at \(\mathrm{x}=1.5\).
