Today we had a continuatiton on proving identities, and we also learned about extraneous roots. The quote before the notes turned out to be very true.. They make no sense. I get how to solve trig functions, but the identities catch me off guard. Once i am told they are there it make sense, but they are going to be tough to memorize, and i have got to make sure i know all the steps and follow them one by one so i don't fall off track because that is very easily done for me.
