the average of the left and right riemann sums is equivalent to the _____ sum. a. triagonal b. middle riemann c. central riemann d. trapezoidal in matlab

main.m
% Define the function to be integrated
f = @(x) x^2;

% Define the interval [a, b]
a = 0; % lower limit
b = 1; % upper limit

% Define the number of subintervals (n)
n = 4;

% Calculate the width of each subinterval (h)
h = (b - a) / n;

% Calculate the left Riemann sum
left_sum = 0;
for i = 1:n
    x = a + (i-1) * h;
    left_sum = left_sum + f(x);
end

% Calculate the right Riemann sum
right_sum = 0;
for i = 1:n
    x = a + i * h;
    right_sum = right_sum + f(x);
end

% Calculate the average of the left and right Riemann sums (middle Riemann sum)
middle_sum = (left_sum + right_sum) / 2;

% Display the result
disp(middle_sum);
