1. One important component of problem solving is to extract general insights from specic mistakes. Find one problem that you solved incorrectly on a previous assignment. In one paragraph, describe the specic mistake you made. In a second paragraph, describe a general modication you can make to your problem solving approach to avoid making similar mistakes in the future. (If you achieved a perfect score on all of your previous assignments, describe a general part of your problem solving approach that helps you do so well!) The rectier function ( ) _ 0 if .9: 1(3) and 8(33) 3 x) for all 3:, and 30(1) and r(.r) are both continuous. 2. (a) Explain why 33(33) approximates r(a:) well for large (positive and negative) values of a". (b) Explain why 9(33) approximates r(m) well for large (positive and negative) values of .r. 3. Where is p(x) the worst approximation to Na)? In other words, where is the vertical distance between the two functions maximized? 4. (a) On the interval (700, 0), where is 9(33) the worst approximation to r(.r)? You may not be able to determine an exact mvalue, but nd the integer a
