On this sheet, is there anything that we DON'T need to know or do we have to memorize everything on it? I feel like may be there are too many in this sheet.

woahh! thats like a trig course worth of formulas ...

the DAT bootcamp math formula sheet is a good resource for everything we need to know.

Like @jjj7236 said, the Bootcamp math formula sheet is good. Destroyer is also good with the formulas it lists in the beginning of Math Destroyer. If you want to memorize everything that might be covered concerning that link I'd make sure I had down the tangent identities, reciprocity identities, pythagorean identities (not likely but still possible), even/odd (could come up), law of sines and that's probably it. If you really want to get crazy you could memorize the double angle and sum difference identities but I think that's a waste of time.

Edit: Oh and memorize the unit circle and common calculations with those if you're feeling up to it.
