Description (last modified by )
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
This was reported in ask.sage: an integral with arccos wrong
