2 Stationary points
For each of the following functions
. Find the stationary points.
• Using the second derivative test, determine whether the each of these points is a saddle, a minimum
or a maximum.
Note that you must explain every step of your calculations.
1. f(x,y)=³-x+y³-4y
2. f(x,y) = (x - 1)(x+2)(x - y) (y + 1)
3. f(r,0)=sin²0. For this question, you can either use the gradient (and second derivative test)
in polar coordinates, as derived in the videos, OR, convert the function first to Cartesian coordinates,
and then proceed as usual.
