Problem 51P Problem 51PIn this section we computed the single-particle translational partition function, Ztr by summing over all definite-energy wave functions. An alternative approach, however, is to sum over all possible position and momentum vectors, as we did in Section 2.5. Because position and momentum are continuous variables, the sums are really integrals, and we need to slip in a factor of 1/h3 to get a unitless number that actually counts the independent wave functions. Thus, we might guess the formulawhere the single integral sign actually represents six integrals, three over the position components (denoted d3r) and three over the momentum components (denoted d3p). The region of integration includes all momentum vectors, but only those position vectors that lie within a box of volume V. By evaluating the integrals explicitly, show that this expression yields the same result for the translational partition function as that obtained in the text. (The only time this formula would not be valid would be when the box is so small that we could not justify converting the sum in equation to an integral.)

MATH 10B Lecture #10 Notes Ivan Lopez October 25 2016 End of Section 6.1: Line Integrals 3 De▯nition: A simple curve in the image (range) C of a map c : [a;b] ! R (or R ), which is 1-1 (one-to-one, which is to say that C(t ) =1 6 C(t 2 if t16= t2and does not have any self-intersections except possibly at endpoints). In addition, the curve is a simple closed curve if c(a) = c(b). Remark: A curve is called simple if it is both x-simply and y-simple. Let us now focus on how line integrals are independent of reparametrization. From the this image, we can make the following statements: We have a curve C, where we have c : [a
