hi, I have to generate a random vector |Q>, which has the following form: |Q>=a*(1,0)+b*(0,1), where |a*a|+|b*b|=1 and (...,...) is a 2 dimensional column vector. This is a linear superposition of two vectors simply and the values of the vectors change between [0,1] randomly. I...

great! but pie = 3.141592... and this is not help.

Maple "simple" integration HELP ! hi, somebody please try to help me to integrate an expression in Maple or Mathematica or other... I don't have any of these programs and I don't want to solve it "by hands", because it seems to be long... You can find the expression in my .pdf attachment...

ok. See the attachment.

hi, Is it true that 2*(p+p_1)p_3(p+p_1)p_2 - (p_3)(p_2)(p+p_1)^2 = (p_3)(p_2)(p+p_1)^2 , where p,p_1,p_2,p_3 are four vectors? Or simply: associative this operation?
