Counting number of tests is not a very perspicacious analysis technique.

                                              asin     acos cos/cosh

number of branch cuts                          2       2      0
tests per branch cut                           3       3

Number of special values                       1       1        1

Does naive implementation suffer               yes     no       no
from catastrophic cancellation?

Total number of tests                           8       7       1
