Let $f(x)=arctan(x)$. Use the derivative approximation:

${f}^{\prime}(x)=\frac{8f(x+h)-8f(x-h)-f(x+2h)+f(x-2h)}{12h}$ to approximate ${f}^{\prime}(\frac{1}{4}\pi )$ using ${h}^{-}1$ = $2,4,8$ . Try to take $h$ small enough that the rounding error effect begins to dominate the mathematical error. For what value of h does this begin to occur?

If you are looking for linear approximation examples for your engineering course or you need to provide an approximate in Psychology or Sociology as you are estimating the data available, you will find great answers offered by your fellow students. These will serve as the templates for your writing. As the questions are being asked, you will learn that most approximation problems are approached with the help of linear equations and logic. If you find it too challenging, try to reverse-engineer some of the solutions first to see what formulas and approximation methods have been used to find the answers.
