forum Does anyone know what Area, Perimeter, Coordinates, and Components are?

I mean I know what they are except for Components and I know how to find area and perimeter, but I don't get the coordinates and components and that stuff? It's for a project.

I assume this is for math or something along those lines? What are the details of the project?

find the area, perimeter, coordinates, and component of the ship I had to draw.

Are you working on vectors? That's the only thing I could find related to math and "component."

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh, I think it's coordinate plane. Whatever that is

Jeez… what are they teaching in math nowadays??? Uhh dang idk
This is the first result I got:
"The component form of a vector is the ordered pair that describes the changes in the x- and y-values…"
Does that sound familiar?

Yes, but wth is a vector?

Umm you learn about them in geometry and then more in-depth in trig. What math are you in?

…………pre-algebra?

Ok, so you drew a ship on a coordinate plane? If it can be divided into geometric shapes then you can find the perimeter and area pretty easily, and I guess the coordinates would be key points of the drawing (if you drew it by connecting dots with straight lines, find the ordered pairs of the points)

Okay, so numerical data can either be scalar (just measured in numerical value) or vector (measured in magnitude and direction. For example, speed is scalar, and velocity is a vector. (with speed, you just give mph, and it's always positive, whereas for velocity it can be positive or negative depending on whether the object is moving forwards or backwards.) I'll try to explain a little more in a minute. I haven't seen this stuff since my sophomore year of high school, so I'm sort of refreshing myself a bit too.

Look in your textbook and notes from class for the definition of components then… and if you don't find anything, email/ask your teacher if it's not due tomorrow.

Oh ok, hmm makes sense let me try it.

y'all see thats the problem, she hasn't even taught us this yet, I only learned area and perimeter from tutoring..

Her exact quote : "I haven't learned any of this until high school, but this should be easy enough for you."

Like we're in 7th grade?

Gotta love when teachers pull that on you. But yeah, no. I don't think we did components/vector stuff until precalculus.

Ugh, I hate those teachers. Like, "oh; you're in an advanced math class so I shouldn't have to teach you anything because you're smart enough to figure it out." No, dumbass, we can learn what is taught to us quickly, not absorb knowledge out of thin air through osmosis.
Sorry for that rant…

IKR, It's stupid, like you're suppose to do your job and teach us!

If it isn't in your textbook or other given materials and she didn't teach it to you, then you shouldn't be responsible for knowing it. Just do the area/perimeter/coordinates for now and if your teacher gives you crap about it then tell her to do her job. (Or if you don't want to do that, talk to other people who did the project before your math class; they can probably help a lot more than we can.)

Oh, no. You're absolutely right. That's one of the reasons AP calculus was the worst. The teacher kind of assumed we knew stuff… and also for years, teachers assumed we knew what logarithms were, but we didn't. And it's wild how different college is. You get in there, and they assume you know literally nothing except any pre-requisites that you basically have to prove you know anyway.

But I think I understand component form. It might be hard to explain without images, but how much can you tell me about it already? I can maybe gauge how much I may need to explain.

I know absolutely nothing, sorry….

Oh, wait. Have you tried khan academy yet? That might help some.

Yeah, thats what I'm doing and I'm still not getting it….

Jesus… it is precalculus. I was advanced track, and I took that in 10th grade.
Okay, this might be a little rushed, as I have a calculus exam at 8 AM tomorrow, but I'll try to explain as well as I can.
So you've got a graph. The x-axis increases from left to right, and the y-axis increases from down to up. You're given two points on the plane. If you look at the points, you see there's one where x=1 and y=5, and the other where x=7 and y=16. To put this into component form, you would document it <x1, y1> and <x2, y2> Soooo, your notation would be <1,5> <7,16> or something really close to that. Anyone correct me if I'm wrong.

Yeah, like I'm trying to see if I can figure out what my brother is doing in math to compare to this, as he's in the same grade as you, but I don't really live with him anymore, so I'm not very aware.
