24008 exponential integral of arccos mforets "Maxima interface returns a wrong result of this definite integral:
{{{
sage: integrate(exp(arccos(x)),x,0,1, algorithm='maxima')
-1/2*e^(-1/2*pi) + 1/2
}}}
while it should be:
{{{
sage: integrate(exp(arccos(x)),x,0,1, algorithm='sympy')
1/2*e^(1/2*pi) + 1/2
}}}
