4. Consider the following improper integral. pler Jo 23/4 dr. (a) Evaluate this integral by first removing the singularity by a change of variables, and then applying the composite trapezoid rule. Plot the absolute error as a function of stepsize h on a log-log graph. (Hint: once you have made the change of variables, use maple to evaluate the integral to 16 digits precision. (b) Evaluate this integral by using a combination of composite trapezoid rule at interior points and the mid-point rule at the first point. Plot the absolute error as a function of stepsize h on a log-log graph. (c) Comment on any differences between the results obtained in (a) and (b)
