comment Definite integral evaluation
It would help if you eliminated all the unnecessary parentheses (and, for that matter, the superfluous * signs). Also, simplify by substituting, say, {v/L -> k, a^4 A -> b}. Still, with those changes and by taking, say, {R -> 1, k -> 1, b -> 1}, Mathematica does not give any closed-form antiderivative of the integrand. You may need to use NIntegrate.

Would you share the code for your example?

comment How do I insert a calculated value into a text cell?
sorry, I was wrong about this: definitely the CellPrint[{TextCell... expression does produce a Text cell, just as requested by the O.P.

comment What is the fundamental difference between “PlotPoints” and “MaxRecursion”?
The practical issue is which of the two to use when, in order to improve quality (and perhaps fidelity) of a given plot.

comment Recognize physical constants?
Best would be some on-line app that identifies physical constants, akin to the one that identifies mathematical constants -- the one in the link cited in my original post.

comment Recognize physical constants?
Worked nicely for me to identify 9.81, which is the original example I posted. Sort of worked for 32: the entry in output for "gravity" gives the metric value 9.80665 but not the corresponding English units value.

I'm using 10.3.1 for Mac OS X x86 (64-bit).

when trying to load the .mx file, I get error message "DumpGet::bgabi: File ./nearestPhysicalConstant.mx was written with ABI 32, which is not compatible with this version of the Wolfram Language."

comment Forcing Mathematica to Output $1/\sqrt2$ as $\sqrt2/2$
Is it reasonable to ask why you prefer $\sqrt{2}/2$ to $1/\sqrt{2}$? While they have the same leaf counts, the latter is simpler in that it uses 1 rather than 2. (Too many secondary school teachers incubate a fear of radicals in denominators, insisting that the student rationalize the denominators.)

comment Recognize physical constants?
I was not naive when asking my question! I was hoping there was some resource out there that might be tapped through Mathematica analogous to the resource for mathematical constants that was cited.

What do you expect to see when the values of the function are complex?

Why bother with the Show expression when you can just add to the Plot expression the option Epilog -> Text[...]?
