Avoid use of atan2 in X8 dynamics model

It'd be nice if we could model the alpha curve in terms of sin/cos/tan of alpha instead of as a cubic, since we could avoid the atan2 call to determine alpha for quartic evaluation.

Looks like this would save at least 80 cycles per dynamics model call (about 35% of the total time).
