arcsec
arctan
?

If so, are those even or odd?

Answer 1

sin is odd
cos is even
tan is odd
csc is odd
sec is even
cot is odd
arcsin is odd
arccos is even
arctan is odd

Answer 2

To correct the best answer, arccos x is neither even nor odd. For example, arccos(-1) = pi while arccos(1)=0. You can check is fact if you put it into google also.
