It's been FOREVER since I've used these! Does anyone know a good memorization tool to remember all of them (no soh cah toa hah)

Also, is there a website that has a bunch of problems that I could practice? I'm using destroyer and pulled out every problem with trig identities and did the same with my first topscore test. I just have a problem deciding which identity to use and I figure if I just do a bunch it will become more natural seeing the pattern and knowing which to use.

Thanks!

You could waste a lot of time memorizing trig identities, but i wouldn't enourage it. I only had 2 trig questions on my test and one didn't involve identities. I think that for the 2 questions you might get on your exam it wont make or break you. What are you hitting on your QR sections right now?

I only had one probability problem and t wasn't nearly as difficult as some of the ones you will see in destroyer. It was similar to pulling marbles out of a bag.
