Corrections and Clarifications to the ODE labs in Vol4
A simple typo fix.
Fixed a formula error and removed a problem that would be hard to grade.
Cleared up a notational conflict on how to apply the initial conditions
and how to apply different higher-order ODE solving methods.
Added a *very* brief explanation tying the IVP solving methods to
numerical quadrature.
Merge branch 'master' into ivp
Fixed math typo in the description of the Runge-Kutta 4 algorithm.
Merge branch 'master' into ivp
Removed some artifacts from a merge.
Fixed another math error.
Updated the solutions to the IVP lab.
Some variable name changes in the new ivp solutions.
Merge branch 'develop' of https://github.com/byuimpact/numerical_computing into ivp
A bigger merge... :unamused:.

Spacing, line-break, and labeling style fixes in the lab on the spectral
method.
Commented out several parts of the Pseudospectral lab that the students
have already seen earlier on in the lab manuals.
Some small clarifications to the spectral method lab.
make plotting script consistent

Modify the plotting script to conform with the rest of the labs.
comment out old plots

Also clear figure after each plot.
use relative size for figure

Also removed forced positioning.
