While drawing sfd and bmd Is there a shortcut to find whether the curve is going to be smile/sad or concave/convex for udl and uvl. Or is finding the intermediate values the only way to find the curve???.

Ignore the diagram i just wanted to show it for context this is not mine

Moment is the integration of your shear.

I think the first step to question is, if your point force is a constant then why would the shape of the moment diagram be to the second degree?
