Could somebody help me to solve this integral by using mathematica? Integrate[sqrt[t*(1-t)*(z-t)],{t,1,z}]; t and z reals; z>=0; I have read that the solution...
Could anybody help me to implement this integral in Mathematica? Integrate[Sqrt[t (1-t) (z-t)],{t,0,z}], 0<t<1 and 0<z<1. I know is that part of the solution...
The integral is imaginary: I factored out t^2 in the Sqrt: Clear[f, t, z] f[z_] = NIntegrate[t*Sqrt[-1 + t + z/t - z], {t, 1, z}] Plot[Abs[f[z]], {z, 0, 0.99}]...
... But if you multiply the term under the square root by -1 it is real. separately: If you leave the original factors that Hugo had then the real value comes...

The idea of using gvu like {-1,-1,-1,1} matrix to determine a group seems to work but gives 11 elements with the zero 4x4 matrix. Calculating the group( first...

This result gives a x^8 equivalent function( eight roots) that is asymmetrical and thus has two levels of false vacuum: (*Projective Line*) x1 = 2*x/(1 + x^2);...
