Let's make a homework help thread!:

 1376 Somedude 1337, Mon, 26th Nov '12 4:20:49 PM from LandOfStormsN'Banjos
[up]+[up][up][up] Thanks you guys, I think I got the rest of this.smile

Pretending to be human
Thought I'd resurrect this:

So I'm gonna work with a LM 301 A operational amplifier and first have to find its open-loop gain, open-loop bandwidth, gain bandwidth product, and input impedance as seen from Vi. But I'm kinda lost here...I have no experience with op-amps and no idea what I'm supposed to look for in the op-amp datasheets that helps me to find out these properties. And my entire class knows nothing about it either. Any help will be appreciated.

ARISE long-dead forum thread! AWAKE from your SLUMBER for I NEED YOUR ASSISTANCE!

Specifically, with logarithms. How do I evaluate Log 2 (1/128)? I know how to do logs with whole numbers, but fractions elude me.

Does expressing it as log2(128-1) help you to see the answer?

Is this thread still alive?

...Guys. I'm heading for college again around June, which is the starting classes with my country. I'm nervous, since I don't know whether I'd do well. What if I couldn't get the hang of this again? I'm going to take up BS Psychology, btw. This would be my last chance, and if I do go well, I'd continue my studies further.

So I'm sure I'd do my best into doing the best possible job that I can!

So I was wondering if I could have anybody I could count on this thread, if not could anyone be so kind to PM me to be my study buddy?

Feel free to add me on Skype, if then! :D

I can assure you this thread is not dead, though I don't know if we have any Psych majors here. I know I keep it watchlisted, so I see everything even if it's something I can't really help with.

Hi. Might I request the help of someone in the know-how of some Pre-Calculus? (Or Calculus. Whichever.)

I'm trying to plot the polar coordinate point (0, -π/4).

Do I take that, since r=0, that you can't plot it? Or... something else?

I can try to be of help to any who need it. Subjects I am skilled in the following; General world history mostly. I can give insight into a few more specific time periods as well, such as the World Wars (a lot of people skim over the first world war for some reason). I can also help with English and other language studies, as this is what I spend most of my time doing.

On that note I'm currently learning Japanese, so if there are folks here who can speak/write it, I'd love to chat sometime. (I'm self teaching from interwebz sources and out of the Genki textbooks for now, so if you also have those, all the better.)

I also have general tips for self study and memory retention if anyone is interested these subjects. Studying about studying may seem redundant, but it is quite helpful indeed.

Just don't ask me anything about complicated math. I forgot that as soon as I left school. Though, any other subjects I would be willing to assist on, just so I can study them as well.

If you want help, feel free to PM me. I don't really do much, so I'm usually available. I suppose you can also inquire about other forms of communication if they're easier for you (I'm fond of IRC, Skype, and email more than forum P Ms, myself).

[up][up][up] To expound on what [up][up] said...

Think of it this way. You start at the origin. Then you move 0 units in the direction of -π/4. But since you're moving 0 units, you're not moving the point at all. So it stays at the origin, (0, 0).

And since you're not moving the point, no matter what your direction is, it'll always be at the origin, as long as r=0.

So, I'm gonna have a Data Analysis exam in less than two weeks.

My doubt is this: In the SPSS program, what's the option that allows me to determinate percentiles/quantiles?

If someone could answer, I'd be grateful.

[up][up]@Quag 15:

Use FREQUENCIES with subcommand /NTILES = n, where n is the number of quantiles you want to divide the distribution into. So to get quartiles: /NTILES = 4, to get (all) percentiles /NTILES = 100, etc.

To get only select percentiles, use /PERCENTILES = [list of values] instead.

Just awesome like that
Okay, I'm utterly lost trying to figure this out. Can anyone tell me in simple terms what a signed deviation score and an unsigned deviation score is (e.g.: what the terms mean and the difference between them)?

there's more than four, so pick: Living organisms
  1. undergo metabolism,
  2. maintain homeostasis,
  3. possess a capacity to grow,
  4. respond to stimuli,
  5. reproduce and,
  6. through natural selection, adapt to their environment in successive generations.

As I recall, what separates "living" from "non-living" is actually hard to pinpoint. There are things in this world that seem to be on the borderline (an oft-cited example being viruses), blurring the difference. There are common, widely-accepted guidelines, but mostly it boils down to "you'll know it when you see it".

That's just not natural.
I need some help! I've got this Math B assignment, and I was doing Grade 12 Math B, but because sites like this ruined my life I didn't do assignments and stuff so I went back to Grade 11 Math B (the grade I'm actually in). It's been so long since I've done this topic I've forgotten what I'm supposed to be doing here.

I need to find the approximate instantaneous gradient of a function on Excel by using small changes in x of 0.0001. I've forgotten how to do that.

The approximate gradient at a point is equal to the slope of a line tangent to the function at that point. Try to figure out how to use Excel to generate that slope. (You can keep asking questions too, but the more you figure out for yourself, the more you learn).

All right, this thread's been a bit quiet but I desperately have a math question. For our Calc test, we're supposed to be able find limits and removable discontinuities WITHOUT THE GRAPHING CALCULATOR! How would one go about doing this? Thanks all.
