This document is a workshop presentation on partial differentiation. It provides the partial derivatives of the function f(x,y) = 5x^3 - 4x^2y + 3y^2. The specific partial derivatives calculated are: i) fx = 15x^2 - 8xy^3 ii) fy = 12x^2y - 6y iii) fxx = 30x - 8y^3 iv) fyy = 24x^2 - 6 v) fyx = 24xy^2 vi) fxy = 24xy^2
