Final exam scores and course grades are now available on Catalyst. Have a good break!
I will be holding an office hour on Friday, 1-2 PM, if you would like to see your graded final exam then. You may also stop by any of my office hours during Spring quarter to see your final.
Final exam stats: n=45; min=16; 1st quartile=66; median=75; 3rd quartile=83; max=99.
I hope to hold an office hour on Friday when you can stop by and see your graded final. I'll announce a time later this week after I'm sure everything will be graded by then.
Here is a review sheet for the final exam.
Today's lecture was a bit rushed, especially toward the end, so I've written up complete versions of the mixing tank examples from today and Friday. They are here. I think it worth a read as you prepare for the final exam.
The answers to the second midterm exam are now in my archive (link at right).
Writing Problem #3
Let f be a strictly increasing or decreasing function. Let R be the region in the first quadrant bounded by y=f(x), x=0 and y=b. Suppose R is revolved about the y-axis to create a solid of revolution. The solid is then filled with a material (e.g., water, dirt, etc.) with density δ. Explain how to determine the work to move all of the material to the top of the solid.
Compare this to the process by which you would calculate the volume of the solid.
Determine the ratio of the work required to empty a cone to the work required to empty the same cone, inverted.
Do the same with a finite piece (including the vertex) of a solid formed by revolving a parabola around its axis of symmetry.
The "solutions" to integrals 16 and 25 had some errors. They have now been corrected.
Here are hints and partial solutions to the integral handout.
Writing Problem 2
Give upper and lower bounds on the smallest n such that n! has
1,000,000 digits.
Due February 19, 2010.
