This exercise highlights a classic subtlety: . The failure of differentiability is due to the term ( -hk(h+k)/(h^2+k^2)^3/2 ) with angular dependence. The directional derivative formula ( D_v f = v \cdot \nabla f ) fails because the derivative is not a linear map — a key warning for students moving from single to multivariable calculus. : Solving first and second-order linear equations and
