This is C language NOT C++ This is C language NOT C++ This is C language NOT C++ For the following program, you should run each of them using Dev-C++. You answer should include screen shots of your code and program outputs as text. Your programs must be commented. The definite integral of f(x) over an interval [a, b] using the Trapezoidal rule is given by: integral_a^b f(x) dx = h/2(f(a) + f(b) + 2 sigma_i = 1^n -1 f(x_i)) Where, n is the number of subintervals and h is the width of each subinterval. Write a complete C program that implements the Trapezoidal rule to approximate the following integral. integral_2^7 x^3 cos(x)dx (assume n = 200)
