But in A it cannot be slope and deflection equal to $0$ since they do not have any type of support, if you look at the support it is only found in B $($mobile support$)$ and in C $($fixed support$),$ in any case consider the jumps of inertia and solved by the conjugate beam method.

$($a$)$ Encuentre la pendiente y la deflexi$$n en A en la figura. $($b$)$ Determine la ubicaci$$n y la

magnitud de la deflexi$$n m$$xima en el tramo BC $.$

$($a$)$Find the slope and deflection at A in the figure. $($b$)$Determine the location and magnitude of the maximum deflection in section BC$.$

Note that in section AB and section CD the inertia is I and in section BC the inertia is $2$I
