Hi,

I'd like to buy a Vietnamese cookbook in Vietnamese (or where there's also a list of ingredients/directions in Vietnamese as well as English) as a gift to someone. Can you suggest a few?

If you do, what product and what do you think of it? As good as the original brand? Worse? I'm talking about drugstore beauty supplies--Neutrogena, Clearasil, etc and I'm curious about the facial products in particular. For things such as nail polish remover and cotton pads, I don't think it's as important to compare to name brand.

Recently I've tried the Olay Daily Facial Cleansing Cloths in the CVS brand, and they've been pretty good. I, however, haven't used the Olay brand of this item in quite a while--probably in 2 or three years--so I can't really compare them. I'm wondering if other store brand products that work well enough and can save an extra few dollars here and there. :)

(I'd greatly appreciate opinions from only those who HAVE tried store brand beauty products. Thanks!)

Hi,

I'm currently a college student and I'm looking to get a credit card to start building on my credit. Can you explain how it works--ie: APRs and interests-- and what I should look for when choosing a card? Any that you would recommend to a first time card owner?

How often should I use it--is three or four times a month for say $50 too little?

I know that I could get one of my parents to co-sign it, but I was hoping to do this on my own. Is that smart or would it be better for me to do this with the help of my parents? (Not meaning that I would hide the fact that I got a card from them.)

I don't know too much about credit cards, so any information would be great. Thanks!

Finally, random question: I've over-drafted on my debit card twice when I was younger--about when I was 16years old or so for amounts less than $20. Will that have negative effects on my credit?

1)

dx/dy=x(y^2)

where y(0)=1 and change in x=1

Estimate y(2)

2.

Integral of (1/(3x-2)) from 1 to 0

Thanks.

The population of the world was about 5.3 billion in 1990. Birth rates in the 1990s ranged from 35 to 40 billion per year and death rates ranged from 15 to 20 million per year. Let's assume that the carrying capacity for world population is 100 billion.

a. Write the logistic differential equation for these data. (Because the initial population is small compared to the carrying capacity, you can take k to be an estimate of the initial relative growth rate.

b. Use the logistic model to estimate the world population in the year 2000.

How do you solve the differentiatial equation y'=x+y by making the change of variable u=x+y?
