Dec. 12 notes
Went over homework problems: p. 372 1,7,11,15,23
If the critical point you evaluate in the second derivative is 0 then it is now a point of inflection.
If the critical point you evaluate in the second derivative is positive then it is concave up and the point is a minimum.
If the critical point you evaluate in the second derivative is negative then it is concave down and the point is a maximum.
In order to be a maximum or a minimum the first derivative has to equal 0.
On AP exam you have to state your justification not just show it. Example: It is a maximum or a minimum on the second derivative test
Worked on problems below for the rest of class.
Homework for next class: p. 530 1, 3, 4, 6-10, 12
