  1. I hope this link works: http://www.welltrainedmind.com/forums/showthread.php?p=702470 The post is from Lizzie in Ma. The book is apparently tentatively titled "Physics after Arithmetic"
  2. Unless your kid is afraid of the dentist/likes to bite (just kidding :)), I can't see why he'd need nitrous oxide for a sealant. I had this done at roughly that age and it was no big deal, it just tasted funny. Definitely if you don't trust the dentist, go for a second opinion. Ask around maybe? I found my current dentist through word of mouth and he's been terrific and also understood my financial situation and helped make payment plans so I could get the seriously needed work done. He also told me what was 'urgent' and what was 'when they start bugging you.' (wisdom teeth :/)
  3. I don't own this, so I cannot vouch for the content, but it's on my list to buy when I start buying books again. http://rainbowresource.com/prodlist.php?sid=1233091636-1418493&subject=14&category=4006 The reviews on amazon seem good, and the sample on google books also looks good.
  4. Try using graph paper for place value. If he only learns decimals, what happens when he reaches a non-terminating decimal? And as others have stated, there are applications where you might actually need the remainder rather than a decimal -- also, sometimes keeping it in fraction form is much less messy.
  5. Julie, maybe he meant that a fellow police officer knew you and said "She's telling the truth, she's not the type to lie about something like that to get out of a speeding ticket."
  6. Unless she is absolutely positive as to what she is majoring in already, I would strongly recommend not stopping before college algebra. You would be surprised at how many majors need math to some extent, and recalling it after 2 years without using it is difficult. I find this website very interesting. Of course it only applies to this particular school, but it is very nice to have the information together in one spot. http://www.uiowa.edu/~examserv/mathmatters/major_math/major_math.html
  7. Are you drinking the milk whole, and did you drink whole milk before? Jerseys often run at a higher butterfat percentage than the "whole" milk you will buy in the store -- ours average approximately 6%, but we have had individual cows average 8% or higher. This jump could be a contributing factor, especially if you are switching from something like 2%.
  8. I'm not completely sure why the answer key started it that way, but the two equations are equivalent and his method is not wrong.
  9. Seriously -- even if she forgets what a number is, she'll remember later. The important thing now is that she isn't allowed to become convinced that she is either stupid or bad at math, because if she gets that in her head, it'll be really hard to convince her otherwise.
  10. Break them into a small bowl one at a time -- if they look fine, they're fine to use. If they look gross, pitch them. We always followed this procedure when we had hens/roosters running together. We did find occasional partially developed eggs.
  11. I've seen articles in the news about public schools using Dance Dance Revolution to try and get video game kids to move. If they can do it, why not you? :)
  12. Schools in some states, including NY, record grades and GPA on a 100-point scale.
  13. tan (2A) = sin (2A)/cos(2A), so sin (2A)/cos(2A) = 2 sin A. Multiply both sides by cos (2A), you get sin (2A) = 2 sin A cos (2A). Using the double-angle formulas, you get 2 sin A cos A = 2 sin A (cos^2 A - sin^2 A) Subtracting 2 sin A cos (2A) from both sides (so we can factor), we get 2 sin A cos A - 2 sin A (cos^2 A - sin^2 A) = 0. Factoring, we get (2 sin A)(cos A - cos^2 A + sin^2 A)= 0. So either sin A = 0, or cos A - cos^2 A + sin^2 A = 0. sin A = 0 has the solutions of 0 and 180. (not sure if you want to count 0 or not, since you said positive it wouldn't strictly be included) To solve the second factor, recall that sin^2 A = 1 - cos^2 A. Substituting this in, we see that -2 cos^2 A + cos A + 1 = 0. This is a quadratic polynomial in cos A which may be solved by any method you choose; the roots are 1 and -1/2. cos A = 1 has a solution only at 0, and cos A = -1/2 has solutions at 120 and 240. The solutions are 120, 180, and 240 degrees. (and 0, depending on whether you include that or not. I wouldn't, since it says positive.)
  14. Do you mean something like "Why does (2x + 4) - (5x - 3) become 2x + 4 - 5x + 3? If not, disregard everything else I'm about to say. Subtraction is essentially adding the negative; thus, 5 - 3 is the same as 5 + (-3). To make something negative, we multiply by -1. So (2x + 4) - (5x - 3) really means (2x + 4) + (-1)(5x - 3). When we multiply 5x - 3 by -1, we need to distribute the -1, so we get 2x + 4 + (-1)(5x) + (-1)(-3). Now (-1)(5x) is -5x, and (-1)(-3) is +3 (recall that a negative times a negative will be positive), so we get 2x + 4 - 5x + 3.
  15. This is what my mother did with me (a long time ago). I had been in public school and was frustrated and associated math with tedious repetition of stuff I considered obvious. The local university ran Saturday math classes for younger, accelerated students, with homework done during the week. I enrolled in Pre-Algebra, and my mother pretty much filled any gaps as they arose. The progression looked like this. 1st and 2nd -- ps 3rd -- first deschooling, then a few golden step-ahead books/lots of INTERESTING math books 4th -- pre-algebra 5th -- algebra I also hated memorization of any sort of math facts, but in following the university's program we were absolutely not allowed any sort of calculator until we hit precalculus. The fast recall came over time.
  16. Do they not automatically deduct taxes in your state? Even when we were far below the poverty line, they deducted taxes and we had to file for a refund at the end of the year. Additionally, this sort of job often won't hire overqualified people (I and some others had problems with this sort of thing -- you're considered a flight risk or somesuch).
  17. 1/csc0 = 1/(1/sin0). Rewrite the top as 1/1, then apply rules for division of fractions by multiplying by the reciprocal of the denominator. You get 1/1 times sin0/1 = sin0. So true. Use the same technique for the second one. For 3, let theta be 45 degrees. tan 45 = 1, -cot (90-45) = -cot 45 = -1. Since -1 does not equal 1, it's false. Note that you cannot use substitution to show equality, but it does work to show inequality. Equality for one value of theta does not imply equality for all.
  18. If she's going to take a bio for majors class, they may assume that she will have already had high school biology and chemistry. If she's going to take a gen-ed class or a high-school level class aimed at students who have not had biology in high school, they will probably not. Ask the biology department at the school she would attend how much knowledge is assumed from high school.
  19. If his parents refuse to help him to the extent that they will not even fill out the forms for him, tell him to talk to the university he would like to attend. They may be able to work something out -- they worked out a situation with a friend of mine where her parents were separated, but not divorced, and neither parent would help her. I don't know what precisely happened though. At worst, he may end up needing to move out, work for a year, declare himself independent and then go. It is absolutely not too late for him to go to college in the fall -- my youngest brother, homeschooled all his life, decided about 2 weeks before college started that this was the year he was ready. He hadn't taken a standardized test at all (he had always planned to start at community college, but had tentatively planned to postpone it until next year). Because of the lack of standardized test scores, he took their placement tests and an ability-to-benefit test, was placed, and started college on probation. His financial aid was slightly late due to the delay in applying, but it did come in during the semester. He just finished his first semester and was removed from probation.
  20. One of the things that really helps me when I'm incredibly far behind (with anything, not just school) is drawing up a plan for catching up and completion. Perhaps making out a few possible plans or using the ones the lovely ladies here have already posted, showing them to her as a possibility ... getting her involved somehow might help?
  21. I love my PDA! So mine has Adobe on it and reads PDF files. It doesn't work so well with math textbooks because the notation confuses it. It does very well with fiction and would probably do fine for non-scientific textbooks, although diagrams might be a little iffy. The other things that I use the PDA for are: Listening to music (it has headphones and winamp which plays mp3s, but this drains the battery rapidly). Shopping (I know HandyShopper worked on my old Palm. I love the features) Playing solitaire when I'm trapped somewhere and don't want to get into a book ;) Calendar: it interfaces with my computer so both the PDA and the computer remind me of upcoming appointments.
  22. A cow will indeed give milk for longer than a year, but the production for most starts to taper off after a few months and continues to drop. She doesn't dry up when she becomes pregnant, but continues to milk until roughly 2 months before parturition, when she is dried off to allow her to rest, build body energy and nourish the growing calf. The usual custom is to aim for a 10 month lactation and a 2 month dry period, which leads to calving every year.
  23. Is she going to remain with you for high school? If so, do you know what you're using for Algebra II? If not, do you know what the school she's going to go to will use? I'd figure that out first, look at the book, and make sure that I didn't miss something that was presumed knowledge in Algebra II.
  24. With only 3 I'd definitely choose to take them to visit when it's that time of the month, if there's anyone within driving distance at all. It should be arranged in advance, so they know you're coming. If you have a minivan or some such, it's fairly easy to load your little lady up for a romantic tryst, and :auto:. Just be sure you put a tarp down first. (personal experience :))
  25. In general unless she'd dried up less than a week before I wouldn't try to restart a milking goat. Some goats are more obvious about heat than others but in general, signs of heat may include being vocal, being unusually cantankerous, wagging the tail back and forth rapidly and dripping mucus from the vulva. If there is a male goat around it's usually a lot more obvious as they'll run up and down the fence bleating at him. If your goal is milky kids I wouldn't breed them to a Pygmy. If you're going to eat the kids regardless of gender a Pygmy would probably be fine, but I doubt that you want to eat your first set of doe kids. Goat meat tastes (imo) a lot like lamb when from young goats. Note: when you breed them, you're going to have to decide what you're going to do with the buck kids. It's impossible to keep them all and they do need to go somewhere. I also wouldn't just buy a random buck if you were planning on keeping the kids -- you should be able to find one from a decent family of milkers for not much more, and it will improve the value/milking ability of the kids significantly. You can have them ultrasounded to see if they're bred. This might cost a bit -- not sure on current pricing. You can also adopt the 'wait and see' method, but if they are not bred, this would delay your first milk. It should be fairly obvious by the time they approach birth as not only will they start to look fat, but their udders will fill with milk in preparation. It is not as critical to catch them before the season is over as it would be with a standard dairy goat as Nigerian Dwarves are less seasonal about breeding.
