Perhaps a little less problematic is to write Gamma(1/2) = sqrt(Pi) = Pi^(1/2) or omething like that.

The law of sines gives us, for any plane-euclidean triangle's angles A,B,C and respective opposite sides a,b,c, the rule sin A/a =sin B/b = sin C/c = 1/2R , with R = circumcircle's radius. One of the most astonishing and marvelous of all mathematical relations, but I prefer to write it as
a/sinA = b/sinB + c/sinC = 2R .
