MAT B41 wrote their exam today!

The multiple choice have been graded and we got the following information.
It looks like the class did alright, the average is quite good.

Average: 70
Median: 73
Standard deviation: 16.7

These are just the statistics for the multiple choice questions.
The full grades should be available early next week.

Mock Final Exam!

Posted in 2018 -- MAT B41 by pgadey on 2018/07/28

The Mock Final is now available!

Thanks everyone, who came out and wrote today! We had about thirty people in total. The last writer finished at approximated 14:50pm. It seems like the final will take approximately three hours. Please attempt the mock final, it is the best preparation for the real final.

Homework #5 Question 4

Posted in Math by pgadey on 2018/07/20

Consider a solid ball of radius $R$ . Cut a cylindrical hole, through the center of the ball, such that the remaining body has height $h$ . Call this the donut $D(R,h)$ . Use Cavalieri’s principle to calculate the volume of $D(R,h)$ . Calculate the volumes of $D(25,6)$ and $D(50,6)$ .

donut

Several students have asked what $D(R,h)$ looks like. Here are some pictures that I found to illustrate the concept. The donut $D(R,h)$ is the region between the red sphere and blue cylinder. The golden balls below show various views of the donut. The donut should fit between the two planes $z=h/2$ and $z=-h/2$ , so that it has total height $h$ .
