- The Festival of Scholars Coordinating Committee writes:
The Festival of Scholars is a campus-wide celebration of student work. It is an opportunity to discuss research, to exhibit, perform, or appreciate art, and to cross disciplinary boundaries. The Festival will be held on Friday, April 15, 2016. Classes will be cancelled on that day, but you are still required to participate in the Festival, either by presenting your work or attending presentations by your fellow students.

Some code you might enjoy
u0[x_] := Piecewise[{{x - 4, 4 < x < 5}, {6 - x, 5 < x < 6}}]
u[t_, x_] := u0[x + t]
Manipulate[
Plot[u[t, x] - u[t, -x], {x, 0, 10},

Typo in Exercise 1.1(1). The second instance of
should be 
.
The last display on page 4 is garbage. Choosing both
and 
to be 
, we obtain
Minor typo in the last sentence before Important Point 1.2 – complege should be complete.
Last sentence on Ex 1.1 – “Use these eigenvalues and eigenvectors to show *how to* obtain the scaling solutions (1.9) to (1.5).”
Ex 3.1 Dumb typo: last sentence should read “spatial shape being manipulated in time” instead of “spatial shape begin manipulated in time”.
Ex. 3.1 $\phi_1 : \mathbb{R} \rightarrow R$ should be $\phi_1 : \mathbb{R} \rightarrow \mathbb{R}$.
Thanks!
One can also use “\to” in place of “\rightarrow”.
:)
Second function in equation (4.15) should have
in place of 
Halfway down page 28: “Thus the functions…”, but you only define one function. I think you also meant to define $\phi_{-k}(x) = e^{-i\frac{\pi k}{L}x}$
whoops nevermind I misread it.
Near the top of page 129 you write ” 1D-Dirichlet-dnergy-problem” which should be ” 1D-Dirichlet-energy-problem”. Just a baby typo.
Exercise A4 in the appendix has three partial u partial x’s
In Exercise 14.6 (3) you refer to the “IBVP given by (??)”
14.11 (1) the x in the first term should have an exponent of (n+1) and in 14.11 (2) I’m pretty sure it should be negative.
The first bullet point on page 192 in Ch 17 I think should say square brackets rather than round brackets
17.4 you write “if an only if”
