Learning expectations for first midterm
- This midterm will primarily test the material listed below, but anything from the list of learning expectations for midterm 1 will also be fair game on this midterm.
- Find the directional derivative of a function in the direction of a unit vector and understand the meaning of a directional derivative.
- Be able to compute the gradient of a function.
- Know the relationship of the gradient to directional deriviatives.
- Know properties of the gradient: that it is perpendicular to contour lines (or contour surfaces) and that it points in the direction of maximal rate of change of a function.
- Be able to find the critical points of a function, and for functions of two variables, classify criticals point using their discriminant (into local max, local min, saddle, or non-ordinary critical point).
- Find the global maximum and/or minimum of a function on a closed and bounded domain (recall this includes finding critical points on the interior, and also finding max/min of the function restricted to the boundary).
- Solve optimization word problems.
- Use Lagrange multipliers to solve constrained optimization problems.
- Compute iterated integrals.
- Compute double integrals over domains of type I or type II by expressing them as iterated integrals.
- Be able to reverse the order of integration in an iterated integral.
- Express and/or compute double integrals using polar coordinates.
- Use double integration to find the volume under the graph of a function, or area of a domain.
