I did that. he gave us a couple test examples, and they worked.
ALl we are to do is setup the main part of the program, and send the matrices to the functions.
i did tell you how i attempted it. I put it in the program, gave it the function, and that is what i got?
A = matrix of:
0 0
0 0
B = matrix of:
1 -1
0 3
a = matrix:
-2
4
b = matrix:
-1
7
and i solved for x,y . (which is done by passing the matrices to the functions that...
well, problem is, my work, is done by the computer.
my assignment is to do write the main program, use matrices, and get the answer, with given functions (that teacher provided).
all we have to do, is pass the functionthe matrices, and get the PA=LU factorization, and the solve using front and...
I have 2 equations, imaginary ones, and 2 unknowns....trying to solve for them..but the answer i got, works with one, but not the other:
i*Z1 - i*Z2 = -2 - i
Z1 + 3i*Z2 = 4 + 7i
where i is the imaginary number, and Z1 and Z2 are the 2 unknowns
the answer i got:
Z1 : 1.33333 +...
so maybe I can use the fact that if I can draw a geometric dual graph, then it is planar ... so I Just have to prove that I can't draw one?
man, i HATE proofs
ok, here is the question:
Let G be a graph with minimal degree \delta(G) = 5, but suppose there exists only one vertex v\in V_{G} such that d(v) = \delta(G). Prove that G is not planar.
ok, i can do this visually. if i draw the vertex v and its edges to its points, and then draw points...
strong primality test ... ??
ok, bear with me ...
we learned weak primality tests (given n and base a,::: a^(n-1) mod n ::: if it does not equal 1, then its composite, if it equals 1, then MAYBE prime) ...
then we learned strong primes .... think of n-1 = m2^k when m is odd. test ::: a^m...
another question.
what is the independent number/set ?

looking at that, and a problem from my homework which the answer is 4:

i have the answer!
hint:
x (cows) can be reasonably guessed.
then you go from there
(this is how i did it. trial and error.lol)
only problem is, if you have to show work in terms of math, im not sure.
i just tried out various values. took me a couple minutes.
oh ok, so a subgraph can contain no edges .... but that is not induced...in order to be induced, it has to be of the original vertex set with edges (that belonged to the edge set of the original graph) ?
its not a complete graph?
tell me about it.
im pretty decent in math, but the professors (im at UNLV) made it to where i hated physics and i havent learned a thing. i know VERY BASIC physics principles and that is about it.
clearly a ripoff, but my wife got it, and that is how she found out about the high school she went to (Community College High School) ...... which is where she got 2 years of her college work done by the time she finished high school ....
what's the difference between a subgraph and an induced subgraph?
looking here:
http://mathworld.wolfram.com/InducedSubgraph.html
how is the figure K8 ? isn't that K10 ??
also, what is a spanning subgraph?
anyone familiar with this, along with some RSA and calculating large powers with modular arithmetic (im lost at the name of it currently).
i have attached the test that I took last week ... he allows us to take home the exact same test home, and do it again, and he combines the grades ...
that argument is weak ...
if you have kids, then what gives you the right to tell them what they can and cant do, etc?
its not saying that anyone can and cant do, but its the basic rights of everyone to be able to live and do as they please within a set standard ..... a policeman stopping...
if people choose to not eat meat, that is there choice...but once they start trying to preach to me, then thats it ....
i eat meat and im proud of it (i like my steaks bloody rare)
and quite personally, i think PETA goes way to far with its tactics ....
oh, cuz i got 30GB of bandwidth on my domain, of which i hardly ever use up (unless i host large vids and songs) ....
too bad you couldnt move over some of it, hehe
ehh?
is the kinetic energy formula:
K=(1/2)mv^2 ?
and still lost on this part:
since E = 22.5 eV << the positron rest mass (0.5 MeV). The mass is equivalent to the electron mass.
was reading the chapter..and they had a section on circulating charges ... it had an equation relating qvB to centripetal acceleration of:
qvB=m(v^2)/r
problem is, in the question, to find r, we have to know v, which isnt given ?? and also, dont know the mass ?
grrrrr
any help!1??!
sounded like me in my first eng physics class...VERY poor instructor, coupled with a poor physics book
i got a couple books, but unfortunately, didnt really help me much.
luckily, i got by ... my scores averaged at most 45%, but with huge curve, was a B ..... to me, that was a sign of...
