The Jacobian matrix is a 2x2 array of first-order partial derivatives. Its rows correspond to the output components $f_1$ and $f_2$, and its columns correspond to the input variables x and y.

Conditions: The function is a vector-valued map from $R^2$ to $R^2$.; The output components are $f_1(x,y) = x + \sin (y)$ and $f_2(x,y) = y + \sin (x)$.; The matrix is evaluated at a specific point, such as (-2, 1), to describe local linear behavior.
