For problem 2.14 use eqn. 2.3.10 in text.
Now use one or more substitutions to put the integral into
a form which matches one in your
Integral Tables.
Note that the simpler the integral looks, the more likely
you will be able to find it.
In your solution, include the name of the tables you
used and (if applicable) a reference # for which one it was.
(i.e. should be enough info so the reader could go look it up
without too much trouble if
they felt so inclined).
If you try to solve for x(t) (instead of t(x)) you will
likely have major problems
unless you already know what x(t) is!
