Answer:

-1392.09
-1744.43
-1636.41

Step-by-step explanation:

using the given integral

calculate: Δx = (12-0) / 8 = 3/2

Xo = 0, f(x) = $x^3sin(x)$

X1 = 3/2 , X2 = 3, X3 = 9/2, X4 = 6, X5 = 15/2, X6 = 9, X7 = 21/2, X8 = 12

Inputting the given values into the Trapezoid rule, midpoint rule and Simpson's rule to approximate the given integral with the specified value of n = 8
