SOH-CAH-TOA
was the way I was taught at school. Which corresponded to:
sin(a)=opposite/hypotenuse
cos(a)=adjacent/hypotenuse
tan(a)=opposite/adjacent
You can make up your own mnemonic, or use one of these:

For one thing there are TONS out there. There are the trigonometric functions, the relationship between the trigonometric functions, the trig laws for right angle triangles, the sine and cosine law for general triangles ... can you be more specific?
The best way to learn trig formulas is to practice questions and always try to do them. If you try to do them and fail to answer the question correctly, go to your teacher and tell them you did this step and this step and still are unable to come up with the correct solution.
If you can add details on precisely what you want to learn about trig formulas, please do so and I'll edit my response.

If you can master this formula first, most right angle trig will come easy.

The easiest way to learn and remember anything is to understand it.
Memorization is useless, it has no real value to the mind.
Tryderiving the formulas. This will allow you to gain understanding and the relationships beteen them.
In addition, practice is a great tool to test your understanding. However, mere practice isn't the best way to learn. Learning comes in dealing with the actual formulas and understanding their derivations.

It helped me a lot by deriving all basic trigonometric formulas with only a pencil and a paper.

Here is an easy way to remember the definitions of sin, cos and tan of an angle of a right triangle:
sin = O/H (opposite over hypotenuse)
cos = A/H (adjacent over hypotenuse)
tan = O/A (opposite over adjacent)

do the simple sums using formulas and write each formula 20-25 times every day for one week and it will automatically registered in your mind

practice tons of questions using trig. formulae.. and after a while you'll have no problem remembering them, it'll come naturally.
