Ash's 31st Post Part II

So, after feeling blehhh all day, eating soup, and taking a much needed nap, I'm on to Calculus! :)

Since I cannot find my binder and half of my corrections, I'm going to try to blog about things I actually remember how to do!

1. Implicit Derivatives
Take the derivative as you would normally, inserting dy/dx and dx/dx each time you take the derivative of y or x
Solve for dy/dx
FINISHED! =]

2. Min/Max on Calc Portion
Type in your equation
Graph it
2nd->Calc
Either Min or Max
Go a bit left of what you think
Hit enter
Go a bit right of what you think
Hit enter
Go in between those two
Hit enter
VOILA!

3. Definite Integration
Integrate (opposite of a derivative)
Plug in b (bottom number on the S)
Plug in a (top number on the S)
B-A = answer!

4. Disks
Formula: piS(equation)^2dx
Find Bounds (How?)
Integrate using Definite Integration

5. Washers
Formula: piS[(top equation)^2-(bottom equation)^2]dx
Find Bounds
Integrate using Definite Integration

Questions:
~How do you find the bounds for the disks and washers?
~I'm still lost on the ln and e integrations and derivatives...they are so easy when someone goes over them with me, but, I cannot get them on the AP


Each time I see ln, e, trig, or anything remotely difficult, I skip it. I usually do not have enough time to come back to these or if there is enough time, I get so confused. I don't have a specific problem right now, because I don't have my binder, but is there a way to somehow improve my time? I don't think practicing helps me because I still get the same ones wrong even after I correct them! =/
Does anyone have any suggstions? I'd be eternally grateful!
