Enter an expression involving the variable x, the degree of the approximation, and its lower and upper bounds. The computer will then find the least-squares polynomial approximation.
Here is what to put in each box. Function: expression to approximate; steps: precision; digits: digits displayed for each term; degree: degree of the polynomial plus one; lower and upper: lower and upper bounds of the approximation.
Explore the fudged function at different degrees by sliding the variable n.
