You will write a serial program using C programming language to calculate the value of the following integral using midpoint rule: 011+x21dx The formula of the midpoint rule for a function f(x) is given as follows abf(x)dx=h[f(2x0+x1)+f(2x1+x2)++f(2xn2+xn1)+f(2xn1+xn)]whereh=nba a : lower limit of integration; b : upper limit of integration; n : the total number of intervals; h : length of each interval
