Number 9 has to be in quadrant two. (the upper left)

Tan<0 which means X or Y (aka adjacent or opposite) has to be negative

Since Sin=5/12 Y>0 which means x<0

5^2 + X^2=12^2
X^2=119
X= root of 119

Cos= -root119/12
Tan= -5/root119
CSC=12/5
Sec=-12/root119
Cot=-root119/5

Don't forget the negative signs!!

10) So just find a range of values for theta which agree with cos x >0
11) Can't read it properly
12) Oh wait it's just I don't know what that symbol means
13) Just arccos (sqrt2/2) and put it into sin
14) Ditto, arccot
15) Dunno that symbol
16) arcsec

Hope this helps, even though I couldn't help with half of them because of that weird symbol
