Chapter 9.1, Problem 7CP

(a) Use calculus to evaluate the integral 0 1 x 2 x , 0 1 x 2 x x y d y d x . (b) Use n = 10 6 pairs in the unit square [ 0 , 1 ] × [ 0 , 1 ]

to estimate the integral as a Type 1 Monte Cub problem. (Average the function that is equal to xy if ( x , y ) is in the integration domain and 0 if not)
