test quantities with transcendental functions

[rckwzrd]

come up with simple test and use case for quantities applied to a transcendental function. expect this case to throw a dimensionality or related error... due to the nature of passing a dimensional quantity as an argument.

A few transcendental functions:

1. sin
2. cos
3. tan
4. exp
5. log

thickness calculations obey rules. search for another example. perhaps with log or exp.
