Post #9

Congrats to everyone! We've made it through our fist nine weeks and we're still..a little sane! ha
This past week was the ninth week of calculus, which means it was time for our first nine week exams. Monday and Tuesday we worked on our study guide and whoever had to finish their presentations went up and did them. Then Wednesday was the BIG DAY for the multiple choice part of our exams in calculus. Turns out that 'B-Rob' helped us by taking our best twenty! [Thank God, it defidently helped me!] Next was Thursday's Free Responce section of the exam...it consists of three questions: optimization, looking at a graph and telling the min/max, points of inflection, and concavity of either the derivative of that graph of the original of that graph, none the less we had one almost like that .. just without the graph, only the equation and that was our suprise! We also had to justify for the free responce, which i totally forgot, but I ended up going back and finishing the justification before the bell rang! I PASSED!

We began our second nine weeks Friday by learning Implicit Derivatives which involves x's and y's!
Here's your steps to follow when taking an Implicit Derivative:
1. Take the derivative [like normal] of both sides
2. Everytime you take the devivative of y state it by putting dy over dx or y prime
3. Solve for either dy over dx or y prime

Remember that if you want the slope you must plug in an x and a y value!....if you have an x but no a y [or opposite] plug into your orignal.

I think I understand this now...it's kinda tough for the big ones but..i'll get there!

Once again, CONGRATS to everyone making it through the first nine weeks!
