Trig, unit circle and the DAT

Ok guys this is what I have memorized so far.
Sin^2X+Cos^2X=1
SinX=cos(90-x)
cosx=sin(90-x)
Tan=SinX/CosX
CSCX=1/SinX
SECX=1/CosX
COTX=CosX/SinX

Okay thats all I know. Do you guys think this is enough for the trig on the DAT? I also know the side lengths of 30-60-90 and 45-45-90.
Let me know if I am missing something.
Also the sides for 30-60-90 are l-l-h--> 1-sqrt(3)-2, correct?

yea, some of those are flat out wrong

sin x is just sin x as well as for cos x. it is not 1/cos x or 1/sinx respectively

I think you meant that in a right triangle, the angles that are complementary and add up to 90 degrees can be written as the sin A = cos B or vise versa. Or you meant Csc =1/sin and Sec = 1/cos

haha woops. Sorry about that one guys. I corrected it now. Typed the wrong thing.
So any1 feel ike I should add anything to this?

i think the first one is wrong. i took trig this year in hs but everything is a blur. i think its sinx^2 + cosx^2=1.
