Thank you very much... i know my ramdon generator is bad~~ i will find on some place...:smile:

i generate a sequence of random number in [0,9], and i need to know whether the random number is uniform or not, so i should check how many time of 1 or 2 or 3...had been generated by the generator? but my program is not work!? #include<stdio.h> #include<stdlib.h> #include<time.h> void...

how to do this integration?? \int x^2 [e^{-x^2}] dx from - \infty \rightarrow \infty

what you mean by constant field? can you tell me more?

de Broglie hypothesis is \lambda = h/p how about if p tend to zero... is it wavelength tend to infinite?

em... for the nuclear decay

what is typical enegry?

get it! Thank~~~

yes, it's -48 the answer in book is 3+4i , 4-3i

how many peak sensitivity of the human eye?

z^2 - (7+i)z + 24 + 7i = 0 z= \frac{\ 7+i \pm \sqrt{(7+i)^2 - 4(24+7i)} }{ 2 } z= \frac{\ 7+i \pm \sqrt{-47 - 14i }}{ 2 } i stuck here

you can use taylor expansion to proof this equation

fluid resistance how to know the fluid resistance is depend on v or v^2 ??

what means by quantization?[?]

no no... just like Lorenz attractor, it's a model as atmospheric convection do you what i mean?
