(A) continuous (B) not continuous (C) differentiable (D) None of these 3 If f (x,y) is differentiable function, then (A) only f exists (B) both Sr and , exist (C)only Jy exists (D) neither , nor Jy exists 4. The first term in the Taylor's series expansion of f (a + h,b+ k) about the point (a, b) is (A)-f(a, b) (B) fa+h, b) (C) f(a,b+k) (D) S(a,b) Given S(1,2) = , (1,2) = 0, Jx (1,2) =6 and 5. that Sa (1,2) 1y (1,2) - (1,2) = 72.
