This week in calculus, we were given a packet that goes over all of the things we should know from last year. Obviously, we're going to be using most of these skills throughout the year, and will need to have them fresh in our heads. The simple algebra that was on the first page was incredibly easy, as it should be, from all the practice I've had in the past four or five years. The second page was still quite easy, and only added multiple answers. I struggled to remember phase-shifts and the like, so I wish there was more than one problem in this packet that went over that. Trigonometry and other things to do with triangles I think are easy, and it helps that trig is fresh in my head. Finding domain and range threw me through a loop at first because I can never quite grasp what they're asking at first, but I usually remember quickly. I also seem to forget how to do logerithems every year too, and I also forget how to spell logerithems. Now I'm going to get back to watching Shawshank Redemption.
I took the long way around this problem because I forgot I could just use preportions. I still got the right answer though (I think).
I remembered how to get rid of e, but I forgot how to get rid of Ln.
