This week we went a little further with the subject. we found global extreme values of the functions as well. i realize that i've been weak on quizzes by looking at the results. but the good side to this is after i do the mastery. by the time the exam comes, i just know and find it so much easier. for example i struggled first trimester but exam i got an a-. i really think it's the best idea doing masteries on test and quizzes, because it just shows how it's all about the end not the mid, meaning by the time the second trimester exam comes i will be ready, i just feel calmer taking exams rather then taking the quizzes. even tho i know i can re-make the quizzes but not the exam. how? why? i'm not sure. just how my brain has been working the past trimester.i really dislike the subject of finding the time when the ladder touches the ground at this rate. it is useless in the real work because no one will use any equation like that in every day life. but, if you were someone like a detective or a cop. maybe all these equations will help you alot. robber killed this guy, he went up the ladder, the ladder is still in the same spot, maybe if you put everything together on what happened an equation like this will be very handful. but in daily life. sadly it won't be as useful as one might hope for. i like math that relate to daily life. i become interested when i know that i might be holding on to this for life. other then that i slowly shift, anyway that's about it for this log, next week is the last week before christmas break, so i am very very happy that it's very close, also nervous. if it's already christmas, i wonder how fast the graduation will be here. a few month can flash when there's stuff going on.
