Hello, It is a known bug? Or maybe not considered a bug at all? Quick search does not show anything related...
sage: f(x) = x sage: f x |--> x sage: integral(f, x) x |--> 1/2*x^2 sage: integral(f, x, 0, 1) x |--> 1/2 The last line shows 1/2 as a function of x, but it is not a function anymore, it is a number. It gets worse with multivariate functions: sage: f(x, y) = x + y sage: f (x, y) |--> x + y sage: integral(f, x, 0, 1) (x, y) |--> y + 1/2 sage: _(3) y + 1/2 I think that here integral definitely should return a function of y only and if I evaluate it at 3 I get 3.5.
