The expansion of f(x,y), is |
| A. | f(0,0)+ ([x frac{ f}{ x}+y frac{ f}{ y}]+ frac{1}{2!} [x^2 frac{ ^2 f}{ x^2}-2xy frac{ ^2 f}{ x y}+y^2 frac{ ^2 f}{ y^2}]+ . ) |
| B. | f(0,0)+ ([x frac{ f}{ x}+y frac{ f}{ y}]+ frac{1}{2!} [x^2 frac{ ^2 f}{ x^2}+2xy frac{ ^2 f}{ x y}+y^2 frac{ ^2 f}{ y^2}]+ ) |
| C. | f(0,0)+ ([x frac{ f}{ x}+y frac{ f}{ y}]+ frac{1}{2!} [x^2 frac{ ^2 f}{ x^2}-2xy frac{ ^2 f}{ x y}-y^2 frac{ ^2 f}{ y^2}]+ ) |
| D. | f(0,0)- ([x frac{ f}{ x}+y frac{ f}{ y}]+ frac{1}{2!} [x^2 frac{ ^2 f}{ x^2}+2xy frac{ ^2 f}{ x y}+y^2 frac{ ^2 f}{ y^2}]- ) |
