Numerical Analysis/Computations

1. to solve problems that may not be solvable by hand
2. to solve problems (that you may have solved before) in a different way

• Many of these simplified examples can be solved analytically (by hand)
  $$x^3-x^2-3x+3=0,with solution \sqrt3$$

• But most of the examples can not be simplified and can not be solved analytically
• Mathematical relationships $\Longrightarrow$ simulate some real word situations
