please help me with the loop for trapezoidal method, and how to modularize the functions needed in the program. my code seem to not be applicable for non-zero lower limits. i am lost. #include #include #include using namespace std; // input lower limit A and upper limit B // input number of trapezoids int main() { double a, b, num, givenEq, midEq, width; cout << "Input lower limit (a): "; cin >> a; cout << "Input upper limit (b): "; cin >> b; cout << "Input number of trapezoids: "; cin >> num; width = (b - a) / num; cout<
