Question 574959: this is calculus, I need some help using the simpson rule
Consider the integral (the integral symbol with pi/2 at the top and 0 at the bottom)cosx dx
i)Using 4 intervals appoximate the integral using the Simpson's rule
ii)Determine the actual value of the definite integral
Please help me

Simpson's rule states that

, in this case,





If you were to actually integrate, you would get

evaluated at x = pi/2, subtract the value obtained at x = 0. The end result is sin (pi/2) - sin 0, or 1.
