In the Finite Element Method, which expression is correct for a linear triangular element if S is the shape function, Ae is its area, and K is a constant?

( frac{ partial S}{ partial y}= frac{K}{A_e^2} )

( frac{ partial S}{ partial x}= frac{K}{A_e} )

( frac{ partial S}{ partial y}= frac{K}{A_e^2} )

( frac{ partial S}{ partial x} )=KAe

( frac{ partial S}{ partial y} )=KAe2
