My professor always uses this word in physics which means "it just makes sense that this happens".

it starts with an "i" but i seem to have forgotten the word.

is f(z)=Rez*Imz

differentiable at z=0?

ive got

lim(h->0) = (Reh*Imh/h) = 0 if h=0?

prove that C\[0,1] is open?

also, Re z >= 0 is not open?

arg(z(1+i)/(-1+i)) ? isnt this in the simplest form?

arg(z(1+i)/(-1+i)) ? isnt this in the simplest form?

Im( (z-1) / (z+iw) )

can i further simplify this?

like maybe Im (z + a) ?

|z-1|<1 , |z|=|z-2|

these two equations are together.

i know that eq.1 is an open disk r=2, a=1,

but what is this geometrically together?

Im [ (z+i)/2i ] < 0

am i doing this right?:

Im(x+iy+i)<0

Im(x/2i + i(1+y)/2i) <0

im stuck/././

Im(z+i)<2

what is this geometrically?

we know that Im(z)<2 is the open lower-plane under 2i

find a pair of inverse points in C of the circle, and find an equation in inverse-point form:

|z-1|=2

where do i start?

|z-1|<1 and |z|=|z-2|

what does this look like?

also, does

Re z =/= 0

mean that it is any point on the real axis except 0?

calculate the distance of closest approach between a 15 MeV alpha particle and a gold nucleus(Z=79, A=197)

could anyone suggest a video card which does not require any external power?

i have this old phenom x4 desktop which gets stuck after some time playing diablo 3 on low graphics.

the psu i believe is too low to have a decent gpu with external power attached.

i would assume it has to do with the video card.

let me know of the best models around so i could look up on ebay or somewhere else

fourier coefficients

|a_n| < (constant)/n^2

|b_n| < (constant)/n^2

show that the sequence of partial sums S_N of the fourier series f(x) is a cauchy sequence for x in -pi to pi

ie. show |S_N - S_M| -> 0 as N,M -> info uniformly
