Prove or disprove the following: If f is in L^1[0,1], then limit the integral over [0,1] of x^n*f = 0 as n goes to infinity. I saw a similar example asking to prove that the integral from 0 to 1 of x^2n f(x) dx = 0, and they used algebra of functions generated by {1,x^2}, but we haven't talked about that, so please when you

7. This problem generalizes the factorial function, as in n!=n(n-1)(n-2)...(2)(1), to more general arguments than just the positive integers. (a) Use integration by parts to show that for any positive integer n, the integral with respect to x from 0 to infinity of xne-x is n! (b) Make a clear case that the integral exists
Find exact values for Riemann sums approximating the integral of the function f(x)=x2 on the interval [0,1]. Split up the interval into N equal segments, and find the upper sum (taking the maximum function value in each segment) and the lower sum (taking the minimum function value in each segment). You will need a mysterious loo
Let two long circular cylinders, of diameter D, intersect in such a way that their symmetry axes meet perpendicularly. Let each of these axes be horizontal, and consider the "room" above the plane that contains these axes, common to both cylinders. (In architecture this room is called a "cross vault".) The floor of the cross vau

Compute a triple integral over a specific solid that would be very difficult in rectangular coordinates, but easy in parabolic cylindrical coordinates, u, v, z, where x=(1/2)(u^2-v^2) y=uv z=z You must come up with the solid. Remember that the Jacobian determinant (u^2+v^2) must be used when transforming an integral to this
