Let's say I've got a helical compression spring of a known length and strength, and I want to know how much force it would take to twist the spring around the axis of its coils, effectively making the diameter of each coil smaller, so it acts a bit like a torsion spring.
I know Hooke's law is...
I'm trying to figure out how to integrate a data set, without knowing the function. While doing this, I got to thinking about this:
If the definite integral of a function can be represented by the area under that function, bound by the x axis, then shouldn't:
\int_{a}^{b}2x\frac{\mathrm{d}...
Ignore the box, it's a plot device, that unfortunately has to be completely fictitious.
What about my description of a manifold: does that seem accurate enough for the purposes of a lay-man's understanding?
Hey all, I'm working on a short hard-sci-fi story, and I'm a bit unsure of the foundational accuracy of my work. If anyone is willing, I'd appreciate some critical analysis of some of the appendices, to either make sure I'm kinda on the ball as far as accurately portraying the concepts go, or to...

I'm assuming transfer means from a CC, the site above gives you the required classes by major + the overlap from whichever CC you're transferring from.
Alright, thanks you guys. You've put my worries at ease. Series and sequences were what I was most worried about. I need to review L'Hopital's rule, and probably some of the integration techniques (I zone hard when I'm just doing a bunch of algebra in leibniz notation...)
I'm pretty...
Most Pertinent Topics; Calc 2 --> 3
Heyo,
Posted here a while back looking for books, as I was planning to study over spring and summer before I registered at a CC. Now it's time to pick my classes for my first semester.
So, I was wondering which topics in calc II I should be reviewing...
I'd say that course is much better preparation than AP calculus. There are two AP Calc. classes, AB and BC. AB covers essentially the same material as Calc. I does. Integration, differentiation, applications of both, along with the underpinnings of calculus like limits, continuity, etc. BC is...
I'm in a similar situation as you, sophomore in high school, etc., though I'm leaving HS at the end of this year for a community college.
I started working through Stewart about two weeks ago, currently on the first chapter of integration. It's definitely a good book for a first exposure, but...
I've found the method that works the best for me is to make chapter summaries with all the pertinent information, then study from those. Writing up the summary essentially forces me to read through everything to get a good idea of what's essential, then I can study the most important parts of...
For a physics major, general chem. would probably be more interesting, as it covers more info that would usually be in a physical chem. class than biochemistry.
Myself, I'd go for biochemistry, but I'm planning on majoring in biochem/medicinal chem., so my opinion may be a little biased...
Can't give you any specifics, but look around for the international versions of texts. Black and white, and it's printed like a phone book, but eveything's there, and they're far cheaper than the normal editions.
My family's hosting a German foreign exchange student for the year, and every one of his friend's that I've spoken to has had at least a working knowledge of English, and he said that's pretty much the norm. So you should at least be able to get around without too much difficulty until you pick...
Just rechecked my work, I had written down 25/12 and 35/12 on paper, but when I solved for the angles I managed to plug in two fractions from a different problem into my calc.
New answer is 17.46 degrees.
Edit: I also used the value of sin(θ), instead of sin^-1(sin(θ)), for the degrees.
Alright, I used the ratio between the two triangles to figure out the length of each hypotenuse, plugged everything into Pythagoras' theorem to find the measure of the two opposite angles, then everything went into the Law of Sines to find the measure of x, which I believe to be roughly 25 degrees.
Alright, I feel a tad stupid. I was taking the symbol in front of 1.25 and 1.75 as a theta, not the symbol for diameter. Makes things a bit easier, for the life of me I couldn't figure out how to find the radii. :blushing:
I've now got something similar to this...
Okay, so I now have two scalene triangles that I can prove are similar using the Angle Side Angle postulate, and their shared side sums to the measure of the inner tangent, 5 inches, though I can't see how I can derive the actual measures from this.
I've been taking the values of θ given for...

The Attempt at a Solution
I believe I'm overthinking this problem, at first I...
It's normal not to be able to come up with a solution immediately, I've poured over questions for days, and I've found, after a certain point, it's best just to let your mind take a break, give the subconscious some time to mull it over. For me at least, it seems like if I can't figure out an...
Allendorfer & Oakley's "Principles of Mathematics" is the book I'd recommend. It'll teach you essentially everything you'd need to know before calculus, and covers a bit of calc near the end of the book. Some of the terminology is a bit odd, but other than that's it's a great book.
Also, most...
Larrabee was also suppose to be x86 compatible, vastly simplifying programming for it.
Intel canceled Larrabee recently however, though. They were looking at 2011-2012 release, and with ATI's new 5xxx series cards, specifically the 5870, being able to push 2.7 TFLOPS, and with nVidia's...
That's essentially what I'm doing. Not a GED, but something similar for California (The CHSPE), then over the summer semester take a couple classes at a JC and enroll full time in the fall. After that.. I dunno, some university in the UC system.
Thanks for the book suggestions.
