If we calculate the derivative of devil we get evil, which is another funtion. But when we calculate the antiderivative, of indefinite integral, we don’t get another function, but an infinite number of functions, with the constant c varying between them. That’s because the derivative of a constant is always 0, so the “original” one can’t be found precisely (in our case it was 0).
