This works on sage-8.5:
sage: a = var('a')
: matrix(GF(25, a), [[1,0], [0, 1]])
:
[1 0]
[0 1]
but not on sage-8.6 or later:
sage: a = var('a')
: matrix(GF(25, a), [[1,0], [0, 1]])

This works on my sage-6.1.1:
s = var('s')
def g(s):
return numerical_integral(cos(pi*x^2/2), 0, s, max_points=100)[0]
def h(s):
return numerical_integral(sin(pi*x^2/2), 0, s, max_points=100)[0]
p = plot((g,h),(-pi,pi),parametric=True)

Is there a way to simplify sqrt(some_unit_of_measurement^2) without knowing
what's in the expression? Often a chain of computations will lead to a
result like the following:
7.5 * sqrt(units.length.meter^2)
I would sage to simplify the units and give me
7.50*meter
but haven't foun

Is there a preferred way of taking numerical approximation of a quantity in
Sage with units of measure? Here is a contrived example:
r = 123/47 * units.length.meter
r
area = pi * r^2
area
output:
123/47*meter
15129/2209*pi*meter^2
Now imagine that r is not a literal but the result of other cal
