Oops - don't think you meant that the way it came out. Sine and tangent
approach zero as theta approaches zero, no matter which set of units are
used for theta. The size of the domain of theta over which the
approximation works well is certainly better in radians!


Yep, careless use of the words "in the limit". Should have said "As theta
gets small.
