B$.($HANDS$-$ON PART$)$

Consider the integral $I={\displaystyle \underset{0}{\overset{1}{}}}\frac{1}{1+x}dx$ in Part A$.$ Write a MATLAB code to calculate

its numerical integral using Trapezoidal Rule $T_n(f)$;$n=2,4,8,16,32,$ and to fill in the

blanks in the table below.

HINT: You may use the MATLAB program trapezoidal.m darr for the Trapezoidal Rule

given in Sec $5\mathrm{.}1($Atkinson$,$ Han: Elementary Numerical Analysis, $3$rd Edition$)$ and

make necessary changes therein to produce the outputs required by this assignment.
