Question: exercise 132 the rintercept of the line passing through the...

Question details

Exercise 1.3-2: The r-intercept of the line passing through the points (x1, yi) and (22, y2) can be computed using either one of the following formulas: or with the assumption yl y2. a) Show that the formulas are equivalent to each other b) Compute the x-intercept using each formula when (xi,y) = (1.02. 3.32) and (z2, ya) = 1.31,4.31). Use three-digit rounding arithmetic c) to compute the x-intercept using the full-precision of the Use Julia device (you can use either one of the formulas). Using this result, compute the relative and absolute errors of the answers you gave in part (b). Discuss which formula is bette:r and why
