Problemes al integrar en la versió GeoGebra Classic 5.0.620.0-d
Answered
Bon dia.
He expressat la fórmula de l’àrea de revolució respecte de l’eix X i pareix que tot funciona perfectament, però si la funció és la circumferència de radi unitat i la integral està definida en [0 , 1] o en [-1 , 1] l’àrea dóna negativa.
Mireu el document adjunt.
Atentament
Juanma

I see this. Also in CAS we get the same result.
I'm looping your post to the developers.
What's strange is that if I calculate the integral entering the function as it is (not its name, but its equation), and also the equation of the derivative (not its name f' ), the result of integration is correct.
Thanks, improvement coming soon
Fixed in v625
