The mnemonic I've been using is:
Some Old Hippy Caught Another Hippy Tripping On Acid
(mnemonic for remembering ratios of sine, cosine and tangent)
 Sinb = Opposite / Hypotenuse Cosb = Adjacent / Hypotenuse Tanb =
Opposite / Adjacent
I relate to it better, and therefor the  mnemonic easier to remeber.

When putting together my cheesy little spreadsheet to study angles I
ported some Internet Java script equations for the calculations of the
beta angle from ratio of sinb, cosb, or tanb. I think the porting
(which is second nature for me) was faster in reaching the
destination, but I missed something in sort cutting the journey. my
mind just focuses on things it doesn't understand and dumps everything
else on the subject until the details are tidied up. I just have to go
after it again.

Memorize the square roots of 2 and 3 and how they apply to 45 and
30/60 degree right triangles. You can design a lot of stuff with only
those angles. They are useful in electrical engineering too.
