Just remember these:
sine = opposite / hypotenuse
cosine = adjacent / hypotenuse
tangent = sine / cosine
sin ^2 a + cos^2 a = 1
Remember these first, these are the most important ones.

Sally Can Tell Ollie Has A Hard On Always.
S=O/H
C=A/H
T=O/A
You can remember this phrase to help you with solving right triangles.

Cosine=Adjacent/Hypotenuse
Tangent=Opposite/Adjacent
