Man, I really hate studying for QR. I feel like there are truly no solid resources for it and it seems like we have no solid guidance as far as what to expect. On the ADA's test specification all its says for trigonometry is "F. Trigonometry." Thanks for nothing...

Anyways, enough ranting, back to my question. Which of the following do we need to know?:

Pythagorean identities, sum and difference formulas, double angle formulas, half-angle formulas? What about the law of sines and the law of cosines?

Im guessing its really only the pythag identities??? Anything else recommended in terms of formulas etc. to memorize for trig?

Thanks for your help!!!!

ps. 2 weeks and counting...aaaaaaahhhhh

It's an old thread, but it should give you an idea. Then ask on here, if you have specific questions, probably get better response. i.e. Do we have to know half angle formulas?

I think I'm going to scan in my math formula sheets so that 30983048930 threads like this stop appearing. Then maybe the mods can make it a sticky or something.

lol, they will never stop appearing 🙄 most threads on here you can find posted numerous times. How many times have people asked about RC strategies? no worries, though.
