+\section{Introduction}
+In this lab, we investigate the response of a circuit (seen in figure
+\ref{img:circuit_diagram}) to different sinusoidal signals. We apply
+both symbolic analysis and numeric analysis (simulation) to affirm
+that this causal LTI system will always generate a sinusoidal response
+of the same frequency as that provided to it.

+\subsection{A complaint}
+Cut the standard lab format. I wrote this as a complaint before I
+really started working on this lab.
+
+I'm going to be frank with you:
+
+Completing these labs is painful.
+
+The lab description itself is 16 pages long.
+
+Every part of the lab reads the same way a 4'' paintbrush dunked in a
+bucket of red paint and splattered across a wall looks.
+
+The writer gives a thousand times more information than you need, and
+instructs you to do things .... a million things.
+
+And then, at the end of the lab, a description of what you're actually
+supposed to submit is given.  The two are so loosely connected ... it
+means there is no one good strategy to break things down and start
+working.  You just have to keep reading and re-reading, looking for
+parts or aspects you haven't covered, and then you have to sew all
+those harvested organs of incomplete understanding into a cadaver,
+packing dozens of lungs, livers and kidneys in however they'll fit, as
+though enough organs will bring a corpse to life.
+
+I had a much better time understanding it, now that I'm re-reading the
+whole thing very carefully and following the math being demonstrated,
+but it's no wonder everyone hates these labs.
+
+It's insanely punishing if you haven't read the lab before you start
+doing the procedure.
+
+Did I mention that the lab description (which contains the procedure)
+isn't released until 15 minutes before the Lab section?
