I believe:

sin()=opposite/hypotenuse
cos()=adjacent/hypotenuse
tan()=opposite/adjacent
csc()=hypotenuse/opposite
sec()=hypotenuse/adjacent
cot()=adjacent/opposite

and:
1/sin()=csc()
1/cos()=sec()
1/tan()=cot()
sin^2()+cos^2()=1
tan^2()+1=sec^2()
1+cot^2()=csc^2()

> if I remember right, tan()/sin() is cos()...

tan()=o/a
sin()=o/h
tan()/sin()=(o/a)/(o/h)
=(1/a)/(1/h)
=(h/a)
=sec()

Just a clarification.
