Trig Identities... Anyone have a nice sheet that has them on it?

Question

When I was in school I had a teacher that gave us a really nice one that had all the identities, plus a circle with radian values and such on it.  Unfortunately i lost it :(.. so far i havent found anything close.  Im wondering if anyone out there may have one that is nicely done that might want to share it?

I've been doing this for so long that I've got most of them memorized.

However, drop in at your local university's math department.  Many of them publish little wallet cards with handy formulae on them.  You might want to check out the Chem and Physics departments for other indispensable cheat sheets.

Are you doing A Level Maths? Coz these are all the ones you need for A2.

For the circle, just use Google to search on "unit circle".
