Hey I have 3 little simple math question if anyone can help. It's just lines that I dont understand.
Y is a line in a complex plan that is determined by the origin and the complex number given by the scalar product of 2 vector x and y. It is denoted by (x,y)
Now sigma varies over the line Y' (Y' is symmetric to Y by the x-axis) so that sigma=tz (t is real)
z= complex conjugate of (x,y)(with the line over) / absolutevalue((x,y)). It is the unit vector
everything is good but now they say
sigma*(x,y)=t*abs(x,y). They say this is real. I dont understand
E(j=0,p) = summation for index j from 0 to p
P^(j)(u) is a polynomial in u with power j
E(j=0,p)E(l=o,p) 1/(j!l!)P^(j)(u)Q^(l)(u)*(sigma-u)^(j+l) gives
E(k=0,2p) E(j=0,k (1/(j!(k-l)!)) P^(j)(u) Q(k-j)(u)^k
There exist an ''n'' so that (n-1)x is smaller or equal than.. y.. smaller than nx
for arbitrary x real positive and arbitrary y
n is greater than 1/h. 1/n is smaller than h
there exist an integer m such as
m/n smaller or equal to ..a.. smaller than (m+1)/n. (this is a modified version of the theorem above)
now ''clearly'' (well not for me)
(m+1)/n -a is smaller or equal to 1/n is smaller than b-a.
the right side of this is obvious (stated before) but I dont see why (m+1)/n -a is smaller or eq. than 1/n
sorry if this is not entertaining. I'll post it in a math forum also.
