Slope-Deflection Equations - modified equations for pinned supports

Can you please explain why FEMf=0 but FEMn is not equal to 0 though both are not fixed ( I understood about FEMf=0)?

[@ProgrammedMechanics]

there is a moment at n, but not at f.

[@tanmoysahoo2381]

I have seen in a book. There its considered that both end is fixed then they find fem in both end. I can't find similarity with hibbler's book.

If we consider fem=0 then how can I solve for theta f?
