Please, I want to detail the answer to the second and third questions. Please, I need a detailed handwritten answer

The evolution of the trigonometric function versus is given. in the table below. We want to integrate the function in the interval [0,] using the Traperoid method. 1) Recall the Traperoid Method Formula in the special case (Equally spaced buse points) 2) Using the special case of the Trapezoid Method, obtain an estimate of the integral I in the interval [0,]givenby: 1f0f(x)= 3) Find the step size so that 4) Calculate the number of intervals corresponding to the value
