New issue 1918 by smichr: 1918: sqrt speed up http://code.google.com/p/sympy/issues/detail?id=1918 sqrt had a large time penalty associated with it because of the extra symping that was occuring and because of it using ** instead of Pow.
timeit('sqrt(1)', 'from sympy import S, sqrt')

timeit('1**S.Half', 'from sympy import S, sqrt')
14.745359815283763
timeit('Pow(1, S.Half)', 'from sympy import S, sqrt, Pow')
3.2267961430852097 After this patch, it can be used with less time-worries as sugar for Pow(x, 1/2):
timeit('sqrt(1)', 'from sympy import sqrt')
