Question

find all the stationary points
f(x,y)=1/2x^4+3y^2-6xy

Answer 1

did you solve fx = 0, fy=0

Answer 2

i don't know how to do that...:/

Answer 3

ok, we need the partial derivative of f(x,y) with respect to x , and partial derivative with respect to y

Answer 4

can you please do that step by step i will give you medal

Answer 5

ok

Answer 6

first lets find the partial derivatives

Answer 7

how do i find that?

Answer 8

one moment

Answer 9

ok;)
