solutions manual
I am a solutions manual collector, I offer solutions manual ebook
services
Note:

I have the solution manual + ebook for Fluid Mechanics by Cengel 1st
Ed. let me know if anybody wants it. my email is binbin364@hotmail.com

I made a very simple post that has a lot of detail to explain a rather
basic result that follows from the distributive property because for
YEARS posters on the sci.math newsgroup have disputed it, and it's
worth explaining in enough detail for people to understand how easy

For various reason I've been looking more at my own behavior in
looking at why some of my mathematical research has failed to gain
more mainstream acceptance, and I've had to admit to myself that I've
been looking for failure, expecting it, partly from being a student of

This problem is related to solving a 2nd order nonhomogeneous differential
equations using the method of variation of parameters.
Assume the homogeneous differential equation y''+by'+cy = 0 has two linearly
independent solutions, y1(t) and y2(t)

I was wondering if there is a criterion to determine when a distribution will peak at the mean. Is the existence of a extremun sufficient or is there more to it?
For example, a normal p.d.f. peaks at the mean, but for the exponential there are no extrema. Any help, reference to ...

I'm reviewing calculus (took a few courses as an undergraduate years
ago) by digging out my old textbook and working problems.  I've run
across a few that I can't solve, and the latest one is the one in the
subject:

I am working on a collectable card game as a hobby. I want a
definitive set of cards that I can plan on crafting by allocating 0 to
100 points to spend on creating the card in any 8 areas.
Given 8 possible attributes to each card, ranging from 0 to 100 how

My dynamic geometry sketches Link at http://math.kennesaw.edu/~mdevilli/JavaGSPLinks.htm
has been updated with Desargues' Theorem, Haruki's Theorem, and Power Lines of a Triangle. Perhaps of special interest to teachers is the new investigation "Classifying Quadrilaterals ...

I'm looking for the book:
Multivariate Data Analysis (6th Ed., Hair, Black, Babin, Anderson &
Tatham)
some one help me....

Problem:
The equation of x^2 - 2x + 2y^2 + 8y + 5 = 0 is the equation of an ellipse.
What are the coordinates of the foci?
I am helpling algebra students solve this problem. I tried to recast this

I'm a highschool graduate and I'm going to major in Mathematics this
Fall. I would like to have a foundation in programming so that it
would be useful in my later career as a mathematician with interests
in logic, numerical analysis, formal systems and that sort.

I am showing high school algebra stuents the general form for quadratic
equations: Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0. I also want to show them how
the value of B^2 - 4AC determines that kind of conic is produced. That is,
<0 produces an ellipse, 0 produces a parabola, >0 ...
