Welcome to Jake's section of Math 21a


Announcements

11/7: We are now moving into the third third of Ma21a which I am giving the title "Integrating vector fields."

11/3: Congratulations on completing the second midterm. The global average and standard deviation were 80 and 9, respectively.

10/23: This website is up! I will be updating as I find old worksheets, write new worksheets/notes, and learn html. I urge you all to take a look at the notes. Those are new. They form an organized compilation of all important definitions, theorems, and proofs covered since the first midterm.

Exams

Final: 12/13
Midterm 2: 11/2 (covers in-class material up to 10/27)
Midterm 1: 9/28

Vector fields on S^2! --> .
This is what my design school friend told me is the best way to remember that the surface area of a sphere is 4 pi r^2.
