Consider the following scenario:
We have a number of sequential building blocks (e.g. 12 building blocks , ordered from 1 to 12), distributed randomly (but not necessarily equally) on a number of builders (e.g. 3 builders ). The builders are required ...

Hi,
I have the following problem.
I know the value of Spearman correlation, s, and know that for a sample size
n it is related to Pearson correlation, r by:
s = (6/(pi(n+1))...

Meanwhile, try and post any hint you.
I'll try solving this, just give me some time since I'm not used to solving integral equations.

Looks more.
Of course it doesn't! haha thanks for the help.
Psyzen to the power of 3, but did not multiply by pi.
Plus, I note that you computed 2.2 to the power of 3, but did not multiply by pi.
To 1.25.

Since we know how each of those eigenstates evolve in time, it will be easy for us to figure out... .
A general wave function will be in a superposition of eigenstates .
The stationary states are just a good method to solve the Schroedinger equation.

Hi guys,
I have a couple of questions:
1. Say we have a heat equation u_t+u_xx=0 with a initial value function f(x)
I know that the solution is an integral of a convolution. But if f(x)==x would not u(t,x)=x be a solution of the heat equation? It might...

The fundamental solution as:
\begin{equation}
u(x,t)=\frac{1}{(4\pi t)^{0.5}}\int_{-{\infty}}^{+{\infty}}e}{\pi})^{0.5}
\end{equation}
which clearly doesn't satisfy the equation but satisfies the initial.

Greetings,
I'm trying to teach myself contour integration/complex analysis and
finding it a little more challenging than I expected. To make a long
story short, it's not obvious...

Thus, the
integral from t=w to t = pi-w has magnitude <= R*exp(-rRc)/R * (pi-2w)
= (pi-2w)*exp(-rRc), so goes to t=w is <= R*w/R = w; and similarly....
So for any small w <= t <= pi-w, so |integrand} <= exp(-rcR)/R for such w.

I am trying to find the value of t, when phi = 60? or pi/3 radians.

In mathematical, not programatical ....
Typed exactly
there, in case), and I do not get what you got
EDU
phi =
pi - atan(8/(2*cos(pi*t) + 8)) - acos(1/20*(1/4*(2*cos(pi*t) + 8)^2 +
16)^(1/2))

ans =
1.0000 - 1.1377i.
