determine the value of the constant α so that f(x,y) is continuous at (1,-1) if f(x,y): i)sin(x+y)/(x^(2 )– y^2 (x,y)≠(0,0) ii) α (x,y)=(0,0)

∂^f/∂x∂y = ∂^2f/∂y∂x = -e^(-x)siny + e^(-y)sinx if i'm not mistaken...exist -e^(-x)siny is positive ( e^(-x)siny ) not negative... coz y difftation -siny and difftation -x is -1.. so (-)(-) is positive...

∂^f/∂x∂y = ∂^2f/∂y∂x = -e^(-x)siny + e^(-y)sinx ---> how we get this??
calculus 3
if f(x,y) = e^(-x)cosy + e^(-y) cosx find (∂^2 f)/(∂x^2 )+ (∂^2 f)/(∂y^2 )- 2(∂^2 f)/∂x∂y
calculus 3
find and sketch the natural domain of f(x,y)= √(x+y^2 )/(x^2+y^2 )
