Graduate Deriving the MGF for the Weibull Distribution
In the first url try copy and pasting the whole thing, but taking out the space between the 2 and the F Similarly, for the second url take out the space between the I and the nfinity. If this doesn't work let me know and I'll attempt to repost what I'm trying to show in another format.- donald17

Graduate Deriving the MGF for the Weibull Distribution
I'm attempting to derive the MGF for the Weibull distribution. I know that E(e^{tx}), which equals the integral shown here: http://www.wolframalpha.com/input/?i=Integrate%5Be^%28t*x%29*%28k%2F%CE%BB%29*%28x%2F%CE%BB%29^%28k-1%29*e^-%28x%2F%CE%BB%29^k%2Cx%5D where the parameters are k and λ...- donald17

Show that matrices of defined form have inverse of the same same defined form
Homework Statement Given the set of 3x3 matrices of the form: [1, a, b; 0, 1, c; 0, 0, 1], where a, b, and c are any real numbers show that the inverses of these matrices are of the same given form. Homework Equations Using elementary row operations, transform [A:I] into [I:A-1]. Inverse of...- donald17

Triple Integral in Rectangular Coordinates Converting to Spherical Coordinates
Shouldn't we be integrating the region of the sphere in the -x, -y, +z plane, since z goes from the bottom of the sphere, moved up a on the z-axis, to the plane z=a?- donald17
