Please I want details for each question

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 Trapezoid method. 1) Recall the Trapezoid Method Formula in the special case (Equally spaced base points) 2) Using the special case of the Trapezoid Method, obtain an estimate of the integral I in the interval [0,1 given by : t=0f(n) 3) Find the step size so that 4) Calculate the number of intervals corresponding to the value
