Detailed Description

The lift and drag coefficients of a symmetric foil, and their slopes.

The slopes are returned alongside the values because every caller that wants one wants the other: the fin wrench and its Jacobian are computed from the same angle of attack, and recomputing the sine and cosine twice would be both slower and a chance for the two to drift apart.
