I Let 5 he the unit square: S={[r.yj|:il:.zas:1.il:yl} Suppose we approximate If I .14 by u prisms whose bases are rectangles of length l in the s r-directiron and width % in the y-direction. I How could you piclt test points in each rectangle to ensure that the value of this approximation is [1. no matter what n is? I How could you pick test points in each rectangle to ensure that the value of this approximation is 1. no matter what n is? I Does the fact that both of these approximations are possible no matte:r hour:I man}:r rectangles we use mean that [f .r {IA does not exist? Explain. 1
