This week in math class with learned about the chain rules and finding dy/dx. not only that but finding dy/dx' as well. for EXAMPLE finding y'' of y= cot(x). well, y'=-csc^2(x). so y''=-2cscx(-cscx)(cotx) which equals -2csc^2(x)(Cot)x. it's pretty simple, Finding the second derivative IMPLICITLY is something else we learned about. i found an addicting song i've been listening to as well. if you have time look it up "tuesday" ft drake. by ilovemakonnen. listening to that song none stop with friends. we also took a mini quiz. i got a 7.5/10 but non wrong, meaning how to do it, i just missed a few points on 2 and 3 because i mess up on the last step, and missed half a point because i forgot the c in the equation. other then that i think i would have got a 10/10. with that said i hate quizzes and tests on monday because it makes my sundays stressful if i were to study for it. but oh well. thursday we need a day 1 and day 2 lesson. friday in class my group did number 28 and we found it pretty quickly, we all got it and no one really struggled with the problem like we normally do every ccc. and october is nearly over so that's a bit insane to think about how close 2015 is. other then that i don't really know what to say. this week for quizzes we just took a 4 question quiz that i already talked about. and next week we have a quiz monday. was a good week. have a good weekend!
