    I don't see how that changes the core of the issue: people getting into various lines of work for the wrong reasons.

    It's funny, I often see people on this board rant about people who got into IT during the dot com boom just because it was "hot", and then you get threads like these were people recommend going into nursing for the very same reasons. ;)

    Sorry, not him. This guy was much larger, and probably not older than 25.

    Overweight Mexican comedian?

    Sometime in the last two weeks (since the TV schedule here lags the US', you can never be sure what date the original show aired), Jay Leno had a very overweight Mexican-American comedian on his show, but I didn't manage to catch his name. Does anyone know who I'm talking about?

    can you really get by in europe without a car?

    Um, first of all, not every European lacks a car. But even if a particular European did (although I don't see why this question is not about car-less people in general), they could for instance have had the Quickcrete delivered to their home, and borrowed a friend's car to lug the propane tank...

    Meredith Brooks - My little town? It's a long shot, because it's not particularly folksy and her "little town" is not necessarily her home town.

    Remote starter in manual transmission?

    Nope. I learned this the hard way when I was approximately 6 years old. My father had taught me how to start the car's electrical system (i.e. you turn the key "2 steps", so to speak). One time I decided to go out to the car and wait, and I wanted to listen to the radio, but I turned the key too...

    1 more calc question: How to find eq. of Plane given 2 parallel vectors?

    Solving this system: { x + 2y - z = 2 { 3x + 2y + 2z = 7 yields x = 5/2 - 3/2t y = -1/4 + 5/4t z = t where t is any real. Thus the line of intersection (call it L_1) has the equation (5/2, -1/4, 0) + t(-3/2, 5/4, 1), with a direction vector of A = (-3/2, 5/4, 1). The line given...

    1 more calc question: How to find eq. of Plane given 2 parallel vectors?

    No, that's not really what I'm saying, because it does make perfect sense to talk about parallel vectors. Why, both Planetmath and Mathworld manage to define it... (I curse this forum's markup language!)

    1 more calc question: How to find eq. of Plane given 2 parallel vectors?

    But Armitage, if A and B are parallel then your vector C will also be parallel to both. (Talking about "points on vectors" makes my skin crawl btw, surely "scalar multiple" is what you meant though).

    1 more calc question: How to find eq. of Plane given 2 parallel vectors?

    Howard, my point still stands. He needs more information to be able to uniequly determine a plane. And I don't think he meant non-coincident vectors, if that were so, he wouldn't have specified them using coordinates (which assumes some sort of origin, and that the vectors are "lines" starting...

    1 more calc question: How to find eq. of Plane given 2 parallel vectors?

    You can't determine "the" plane that contains two parallel vectors, since there is an infinite number of such planes. Imagine two parallel vectors in R^3. Consider a plane that contains both of them. Rotate that plane slightly around axis "defined" by those vectors. You now have another plane...

    Need help w/ Calc 3 problem - point of intersection of a Plane and Line

    If the point (x, y, z) lies on the line, then x = 3 + 2t y = 6 - 5t z = 2 + 3t for some real number t. But if it is to lie in the plane as well, then 3x + 2y - 4z = 1 must be satisfied, i.e. 3(3 + 2t) + 2(6 - 5t) - 4(2 + 3t) = 1. Solve for t...

    If x^2 = 3, then x is not sqrt(3), it could be -sqrt(3) as well. (Not that you have to make any significant changes to your solution to take this into account).

    Abstract Algebra. I'm a little bit unclear on the process of finding subgroups.

    <a> is defined as {a^k; k \in Z}. It can be shown that if a has finite order (say n), then <a> = {a^0, ..., a^(n - 1)} (and it can also be shown that every element of a finite group has a finite order). Apply this to your problem (and don't forget to translate everything into additive notation).

    While you could use polynomial division, there is an easier way... If f(x) = kx^3 - x^2 - 5kx + 12 is divisible by (x - 2), then x = 2 is a root of f(x). Thus f(2) = 0. Should be pretty easy from there on...

    Why do people remove the s from maths? ;) But seriously, it's a British thing. Like spelling realize "realise", or knowing that spotted dick is not a horrible penile disease.

    I just realized some simple math too....

    Consider S = {1, 2} and T = {shoe, apple, grape}. Define f: S -> T by f(1) = shoe and f(2) = apple. f is injective, but obviously S != T. Perhaps you meant that |S| = |T| (i.e., the sets have the same cardinality), but that's not true either (as per my example). You need to require that there is...

    Can someone help me with a math problem?

    You /can/ go further and reduce to only linear factors, (a^2 + 5) (a - 11) = (a + sqrt(5)i)(a - sqrt(5)i)(a - 11). Whether or not you /want/ to do that is a different matter altogether ;)

    how to solve log problems with XP calculator?

    Your question is oddly phrased, and I'm inclined to simply answer "by pressing the correct buttons at appropriate times?". For the natural logarithm, press "ln". For exponentiation, use the "x^y" button.
