I need to calculate the characteristic function of an exponential distribution:
\phi _X \left( t \right) = \int\limits_{ - \infty }^\infty {e^{itX} \lambda e^{ - \lambda x} dx} = \int\limits_{ - \infty }^\infty {\lambda e^{\left( {it - \lambda } \right)x} dx}
I have arrived at the...
Find the characteristic and minimal polynomials of
A=[[0,1,1][1,0,1][1,1,0]] (3x3 matrix)
So when I work out my characteristic polynomial I went
det(xI-A)= det[[x,1,1][1,x,1][1,1,x]]
= x(x^2-1)-1(x-1)+1(1-x)
= x^3-3x+2
= (x+2)(x-1)^2
It's...
Can anyone here use Bohr's analysis of the hydrogen atom, to compute the characteristic impedance of the vacuum? And if not, then how would the Bohr model need to be modified, in order to obtain Z0?
Characteristic impedance of the vacuum = Z_0 = 376.730 313 461 ohms
CODATA value...
How can an astronomer recognize a double star from the characteristic frequencies of the light that reaches him from its member stars? I have looked and looked in my textbook but I cannot come up with the answer to this one.
Thank you!
