Today we'll have our first quiz at the end of the hour. We'll
work on Mathematica again: who's got a laptop?
We didn't get a chance to look at all the examples I'd prepared yesterday. To start, have a look at some of those problems.
#30, p. 924
#32
#38
In particular, let's create your own version: you need to know how to
create notebooks of your own (if you don't already).
Some of you are struggling to visualize functions. Take a look at my function slicer, 14.slices.nb.
Change the function, and see what slices look like.
In particular, try a "saddle" -- a hyperbolic parabaloid, like we
saw in class yesterday. You can use either
f[x_,y_]:=x y
f[x_,y_]:=x^2-y^2
I wish that the curve lying on the surface were a little
thicker. Can you use help on ParametricPlot3D (which produces that
curve) to figure out how to make it so?
