Why did the vector cross the road? It wanted to be normal. #3 20090416 20:23:59

Re: few quants problemsHi smiyc86; Just trying the first one yields (1)^4  (1)^5  0 which equals 2 so x = π/2 is one solution. Since sin is periodic with c=0,1,2,3... are all solutions. There are also complex solutions but I could not get them without resorting to an iterative method so I left them out. bobbym Last edited by bobbym (20090417 22:06:33) In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #6 20090422 18:19:50
