hey guys,
We have a design project where we are supposed to design something cool to machine and later auction it off. My group has already come up with a plan to build a small stirling engine. I've been thinking if there could be anything we can add on to it, like a useful/fun addon...
Thanks emiltr, the books seem pretty good. though the second link seems pretty scary. It is more like a proofy high level math course rather than an engineering course with applications. I've looked through the table of contents and there is nothing that strikes me as familiar . Let's see.. we...
Hey guys,
I need a book that can teach me system dynamics, here is what they teach in the course:
Linear time invariant system, impulse response function, operator, convolution, system characterization, solution of linear ordinary differential equations, Laplace transform and its...
DH you are absolutely wrong, there is no way that integral with bounds of negative infinity to positive infinity, can work out. The whole thing just blows up when i get to the logs part. i get a negative value when converting bases, and the whole thing turns into a mess. So what's up guys, can...
lol... yeah i did treat K as a constant. Well i can give this integral yet another go, might post my work too since i haven't done integrals for a while
to dirk_mec1: it is the 2nd function you listed, sorry for not being clear.
tiny-tim: well k=0 works for all positive values of x and satisfies the first equation. So i guess I'm Sure. also, any positive number k will yield a positive answer which also satisfies the equation. but i have...
Homework Statement
A function f( x ) had the following form : f ( x) = kx^-(k+1) where 1 < x < infinity
a) for what values of k is f a pdf ?
Homework Equations
See attachments (the theorem is included)
The Attempt at a Solution
started out by using the first equation in the...
hey everyone:
Use a definition to work forward from each of the following statements.
b. for functions f anf g the function f + g is convex, where f + g is the function whoes value at any point x is f(x) + g(x).
Definition of a convex function...
i'm sorry mate, u and v are vectors. (and u1 is the x component of u, and u2 is the y component of u, etc.)
and the question was supposed to be:
find the rank and nullity of linear transformation T(u) = ProjvU where v is (1,5). i just assumed that u = < u1, u2>... how do we get a matrix out of...
