Finite Fourier Transform on a 2d wave
How does the finite fourier transform work exactly?
The transform of f(x) is
\widetilde{f}(\lambda_{n}) =\int^{L}_{0} f(x) X_{n} dx
If I had a 3d wave equation pde and I applied Finite fourier transform on the pde for
z(x,y,t)=X(x)Y(y)T(t)...

I'm thinking mean value...
I know that, and it's not really my question unless I misunderstand the applications of what you just said.
My question pertains to the visible nature of it.
I'm having a hard time visualising them.
How do you plot vector fields
How do you plot spanning sets?
How do you tell if something spans a plane, 3d, a line or more dimensions.

1. Homework Statement
F(x,y,z)=0
x=a(y,z)
y=b(x,z)
z=c(x,y)
what does
\frac{\partial c}{\partial x} \frac{\partial b}{\partial z} \frac{\partial a}{\partial y} equal.
2. Homework Equations
maybe you could tell me?
3. The Attempt at a Solution
i've spent hours and hours...
(\frac{\partial z}{\partial x})y
the small y, what does it mean.
the context this is used in is F(x,y,z) where each variable is a function of the other 2 variables.
1. Homework Statement
z=1-x^2-2y^2
find volume under curve
bounded by the xy plane.
is the answer sheet wrong? (see below)
why am i struggling so much with this??!?!?! how do i do it?
2. Homework Equations
according to other answer sheet, it is pi/sqrt 2

1. Homework Statement
prove 0u=0 where u is in the vector space.
2. Homework Equations
the 10 various axioms for addition and scalar multiplication.
3. The Attempt at a Solution
pretty much just
(u+-u)u=0
or
(1-1)u=0
1u+-1u=0
and then i get stuck. i can prove that...
1. Homework Statement
In set theory, i have a two part question, the first is showing that the system S={set of all real numbers( \Re )}, #}
where a#b=a+b-ab
we have to show that it's not a group.
and then find what c is so that the system = { \Re \cap\overline{c}, # } is a group.

Can you give me 3-10 points why you believe in the theory of evolution and/or the big bang? this is independant of any other theories.
I'd like it numbered. and just brief points, like a topic and brief explanation of why this makes you believe evolution and/or the big bang to be true. I'll...
