Ahem !
On one machine :
sage: sage.version.version
'6.4.beta4'
sage: var("w,t")
(w, t)
sage: solve(-(1/2*sqrt((4*w+1)+1))*t+w==0,w)
[w == 1/2*t*sqrt(4*w + 2)]
sage: maxima.version()
'5.34.1'
Another one :
sage: sage.version.version
'6.4.beta1'
sage: var("w,t")
(w, t)
sage: solve(-(1/2*sqrt((4*w+1)+1))*t+w==0,w)
[w == 1/2*t*sqrt(4*w + 2)]
sage: maxima.version()
'5.33.0'
What are you talking about, guys ?
HTH,
