<description>
Sine cross-propagation validity tests.
The 'u' variable checks for errors caused by poorly interpolating
dependencies. The 'v' variable checks for the existence of the
cross-propagation variable. The results for 'v' should be fairly
similar to those for 'u', but slightly more accurate.
