> I'd be surprised if sin(x)/cos(x) were materially better. Yep. I made the same assumption as you, but then "realised" that to get to the tan tests, we must already have passed all the cos tests, so cos must be okay. I thought I'd written cos tests near pi/2 as well as tan ones, but unfortunately it turns out that's not true. My bad. Those tests should probably be added to cmath_testcases.txt.
