Student Questions 11-28-14
Do you like Dwayne ”The Rock” Johnson?
I do not dislike him.
Could you go over good examples of exam questions in recitation?
Absolutely. A lot of the examples we do in class could show up as exam questions. In
fact I sometimes try to go through harder examples as somewhat of an overpreparation.
What is your favorite calculator game?
Snake.
What is your best tip for waking up on time?
I set two alarms 30 minutes apart. Some people have success in putting their alarm accoss
the room. It all comes down to self motivation.
How many coordinate systems are there?
There are 3 3D systems that we will look at but there are technically infinitely many
because you can make up your own system. We will unfortunately skip this section in
the book. It is the last section in the multiple integral chapter on substitution if you are
interested.
Is it possible to go from Cartesian to volume. For example:
ZZZ
ZZZ
1 dzdydx →
1dV.
The integrals you wrote are the same
Z Z Z thing. The notation for a general triple integral in
any coordinate system is always
f dV . It is just that if you want to set up a triple
R
integral in Cartesian then we know that dV = dxdydz and we would integrate a function
f (x, y, z) over a region that is described in Cartesian.
