To begin, even though this past week has basically only focused on about three things, I must say I was extremely overwhelmed in the beginning. The first worksheet we did I completely screwed up because I used the product rule on basically everything except for on those which required use of the quotient rule, it didn’t click in my head that there was a formula for addition and subtraction until it was pointed out to me. Once I got over that frustration, everything became a lot easier. Average speed and instantaneous speed were easy concepts for me to grasp although when they used the term velocity it threw me off a little bit. The shortcuts made my day even better. My only problem with instantaneous speed is the h’s. when I plug into the formula..f(x+h) - f(x) all over h, I somehow end up with either too little or too many h's, hopefully if i keep practicing i'll get it sooner or later, preferably before the test.
Thankfully I seem to be remembering the newly introduced formulas quite well, including the dirivative formulas. Although I still cant remember the double and half angle formulas, yes, I am the reason we will be taking that quiz over and over again, sorry guys.
Ohhhhh, quotient rule. I get confused on whether or not I’m supposed to use it on a problem within a problem, for example: #27 on the worksheet we had to work on over the weekend,
x(1-4/(x+3))
..it probably isn't as complicated as i'm thinking it is, but i'm stuck.
p.s. anybody else gets mixed up between calc and statistics? i'm all backwards mann.

You need to explain something!
ReplyDeleteyes i've been backwards with calculus and MAO too!
ReplyDeletefor that problem, x(1-4/(x+3)), i think b-rob said that you have to distribute the x, then do quotient rule to get the answer. i'm pretty sure that's how you get the answer. hope that helped.
ReplyDeleteFor that first you would distribute the x like mher said then you would take the derivative of each term and after taking the derivative you would have to use the quotient rule for the second one.
ReplyDeletei thought you had to do the quotient rule first and then after you get that answer use that with product rule.
ReplyDeleteFor the problem x(1-4/(x=3)) I think you would have to do the quotient rule for what's in the parenthesis then use the product rule with what you get and the x
