Numerical Methods in Context

Numerical Methods

  • Numerical methods can be used to model a variety of situations, from the motion of planets across the solar system to the depreciation in a cars value or the fluctuation in crime rates over time
  • Numerical methods can be used to find solutions for questions when analytical methods may not always work or even be possible
  • It is important to understand how each method can be applied to different contexts and the different aspects of a question you may be asked about
  • Questions in context will often ask for an interpretation or criticism of certain parts of the problem
