Math(Correction)
posted by Mark .
Use the given function values and trigonometric identities (including the relationship between a trigonometric function and its cofunction of a complementary angle) to find the indicated trigonometric functions.
Sorry for the mistake. They are two separate functions and i need to find a through d
sec Q = 5 tan = 2sqrt6
a) cos Q b) cotQ
c) cot(90 degrees  Q) d) sin Q

Mark, I see no change in the way you typed your question.
I objected to the line
sec Q = 5 tan = 2sqrt6
which makes no sense.
First of all 5tan is incomplete, there is no angle. I assumed it was 5tanQ
Secondly, the statement led to a contradiction, as I showed in the other post 
I think what Mark means is that
Sec(theta)=5
Tan(theta)=2(sqrt of 6)
Which would make more sense :)
