even Definition and 664 Threads

The break-even point (BEP) in economics, business—and specifically cost accounting—is the point at which total cost and total revenue are equal, i.e. "even". There is no net loss or gain, and one has "broken even", though opportunity costs have been paid and capital has received the risk-adjusted, expected return. In short, all costs that must be paid are paid, and there is neither profit nor loss. The break-even analysis was developed by Karl Bücher and Johann Friedrich Schär.

    Sum over k from 0 to an even n of abs(k/n - 1/2)*C(n,k)=(1/2)*C(n,n/2)

    Odd number of terms so there is a middle term. It is equal to 0. Since C(n,k)=C(n,n-k), abs(k/n - 1/2)=abs([n-k]/n - 1/2), and what's in the abs() increases and is positive k goes from 0 to n/2 -1, the sum is twice the sum of the first n/2 - 1 terms, 2*(1/2 - k/n)*C(n,k). Added C(n,k) from 0...

    1D Groundstate wavefunction always even for even potential?

    Hi! I have calculated various eigenstate wavefunctions for a one-dimensional system of a particle in a potential. The potential is an even function. All the wavefunctions have become either even or odd functions which I understand why. The ground-state wavefunction has always been even, is...

    Diffraction on a body centered lattice, h+k+l even?

    This is in my book: exp[2\pi i(hx+ky+lz)][1+exp(\pi i(h+k+l))]=2exp[2\pi i(hx+ky+lz)]\cos^2[\frac{\pi}{2}(h+k+l)] And in order for the cosine not to be zero, h+k+l must be even when we want to see the reflection. But I think that the result should be exp[2\pi...

    News Free trade reduced to one sentence so even a liberal can understand

    The more people with whom you trade the richer you get, regardless of whether they are across the street or across the world; the fewer with whom you trade the poorer you get. If you could not trade with anyone you would have to make everything yourself and you'd be very poor or dead.
