Well for starters, this week in Calculus we took our first test. I actually did not think it was all that bad (easier than Advanced Math tests). It did not have a lot of questions, which I liked. I think I know most of the stuff we learned this week, just a little hazzy on a few things.
We did some practice on derivatives on Monday and Tuesday for the test on Wednesday. I feel like I know derivatives to the highest knowledge. So let me do an example.
(6x + 5)(7x- 4) we should know that you plug this into the product rule (uv' + vu'). u = (6x + 5); v = (7x - 4). So when you plug in you get: (6x + 5)(7) + (7x - 4)(6). Which simplifies to: (42x + 35) + (42x - 24) = 84x + 11.
I also get how to find relative max and mins by using intervals.
But I do not know the difference between orginal/first derivative/second derivative madness. I get how to do each of them, just all the different vocabulary confuses me. Can someone clarify that for me?

the difference between orginal, first derivative, & second derivative is not much.
ReplyDeletethe orginal..is just that what it means...
there is no derivative..the problem they gave you IS the orginal
the first derivative...deals with stuff like increasing, decreasing, positive slope, negative slope, horizontal tangents and stuff like that. when we went through it...all the arrows she drew, helped alot!
the second derivative is concave up, concave down, and points of inflection, ect...which also goes with the arrows.
the vocab is important though, so look at your notes!
original graph is the one you start with.
ReplyDelete1st derivative is the graph after you take the derivative
and second is the same after yoiu take the second derivative..
or thats how i'm taking it, which is probably the wrong way.
Your first derivative is when you take the derivative of the orginal graph and the second one is when you take a second derivative is the derivative after the first one
