Let’s first make sure we can find critical numbers of a surface. Example – Critical Points Of Multivariable Functions Okay, so let’s identify the critical points for the elliptic paraboloid: f(x,y)=x2+2y2−6x+8y+20 Alright, so we begin by finding the gradient ∇f by computing ...
How to find Stationary Point of a Multivariable function? To find the stationary points of a multivariable function: Take the partial derivative of the function with respect to each variable. Set all partial derivatives equal to zero. Solve the resulting system of equations to find the values of...
