In: Math
ƒ(x,y)= x3 + 3xy2 - 15x + y3 - 15y
For this question i need to calculate the critical points and all local minima, local maxima and saddle points. How should this be done?
I used the basic rule of derivative and remember the partial derivative rule, when use differentiate with respect to x, then y will consider as constant ; and when we differentiate w.r to . y then x will consider as constant. Thank you
