Partial derivatives are a special kind of directional derivatives. Derivative of a vector-valued function f can be defined as the limit wherever it exists finitely. As mentioned before, this gives us the rate of increase of the function f along the direction of the vector u.

are therefore two partial derivative functions. H1= δH(X 1,X 2)/ δ X1 and H2= δH(X 1,X 2)/ δ X2 are the two partial derivative functions. Interpretation H1 measures the rate of change of the dependent variable Y when the independent variable X 1 changes but the independent variable X2 is constant. It is the margin of Y with respect to X 1 holding X 2 constant. H2 measures the rate of

I’m gonna leave the partial partial F, partial partial Y. We want this as a more general function of X and Y. Well we kind of do the same thing. We’re gonna say that this is derivative with respect to X, and I’m using partials just to kind of emphasize that it’s a partial derivative. And now, we’d write X squared and then kind of emphasize that it’s a constant value of Y, plus the sin, and
