    initial v1  
    1 we may want to ensure a symbolic integral wrapper, for instance with (cf. #22138):
    2 
    3 {{{
    4 sage: n = var('n')
    5 sage: integral(x^n*sin(x), x, algorithm='giac')
    6 ...
    7 NotImplementedError: Unable to parse Giac output: integrate(x^n*sin(x),x)
    8 }}}
    9 
    10 but in other cases it already returns unevaluted:
    11 
    12 {{{
    13 sage: integrate(log(1+x)/x, x, 0, 1, algorithm='giac')
    14 integrate(ln(x + 1)/x, x, 0, 1)
    15 }}}
     1see #22891 for "add giac interface to integrate"
