1. ### Calc2: Half Lives and Steady

I know that half lives are relatively simple but I am having an extremely hard time with this lab. Could someone help walk me though the steps? I would greatly appreciate the help!
2. ### Calc2 Power Series

I cannot figure this problem out for the life of me.
3. ### Calc2: Not sure where to begin...

Hey, everyone! I have a test coming up next week and I'm practicing for it (so, the questions within are exclusively for my gain, not a grade) and there's a few problems on the book that I can't seem to get. Question #1: Sketch the region enclosed by \text{y}=8x+2 and \text{y}=5x^2. Decide...
4. ### SOLVED Find the length of the curve? NO bounds are given.

Find the length of the curve? NO bounds are given. ---------------------------------------------------------------------------------- length of the curve formula using wolframalpha I got this int sqrt( 1+ ((1-2 x)/(2 sqrt(x-x^2))+1/(2 sqrt(1-x) sqrt(x)))^2) dx -...
5. ### SOLVED Integration.

How to do the second part(Wondering). I did the first part by normal integration.
6. ### SOLVED Integration Problem....answer check???

Here is the question This is my attempt. Is this correct?
7. ### SOLVED find the volume of the curves rotated about the x-axis

the endpoint comes -1 and 1 and I am taking the integral of ((9/8)-x^2)-(x^2/8)....and then multiplyig by 2pi. the final answers come 3pi. Any help thanks
8. ### SOLVED Calc2...Finding the volume

This is what I have done: 1) The end points are 8 and 3. 2) then I am taking the integral of y = -x^2+11x-24 and then multiplying by 2pi. the final comes 125pi/3..which is wrong. Any help thanks
9. ### SOLVED Solve the integrals for the area

What are the enpoint of these integrals?

11. ### Volume of curve on graph

Refer to the figure and find the volume generated by rotating the given region about the specified line. a) R1 about OC
12. ### solving diffyQ for calc2

I am having trouble towards the end of this problem: dy/dx=(e^(y)sin^(2)x)/ysecx towards the end i get (y^(2)/2e^(y))=sin^(3)x/3 i am not sure really how to isolate y Can anyone please help?
13. ### base integrations / evaluations (calc2)

Can someone please tell me if I am doing these right? (Just finding the anti-derivative) 1. http://www.codecogs.com/eq.latex?\int_{}^{}\sin\left(8z-5\%20\right) My answer: -cos (4z^2-5z) (not sure if I have to follow the chain rule in this or not?) If not I think this is right. (Evaluation)...
