okayyy, so calculus.
the first part of the week was stressful because we were getting ready for
the test, but after that i was alright. we reviewed infinite and finite
limits that we did at the end of last year in advanced math. thankfully that's
one concept i understand.

the limit rules are stuck in my headd.
if the degree on the top=degree on bottom the limit is the coefficients.
if the degree on the top is greater that the degree on the bottom the
limit is plus/minus infiniti
and if the degree on the top is less than the degree on the bottom the
limit is 0.
--horizontal asymptotes were also easy to remember.

the days after the test we learned on brandi's handy dandy projector.
..the first day we got our definitions, which are all easy to understand, especially
after hearing kaitlyn repeat them over and over and over again =)

as far as figureing out the derivatives goes, i was confused for quite a while.

i get the whole.. if the slope is positive, it's increasing and if the slope is negative, it's decreasing concept and the difference between concaved up and concaved down but i just don't know where to begin deciphering between derivatives and i forget to set up intervals.

  1. you're basically just trying to keep the terms straight when "deciphering between derivatives". However, when you are doing the First Derivative Test, you are dealing with the First Derivative.

    You only have to set up intervals when they as you to find the intervals or when they ask yo for the extrema (maximum/minimum).

    Just a reminder.
