MHB Finding Vector and Parametric Equations for a Segment Joining Two Points

[ineedhelpnow]

Find vector and parametric equations for the segment that joins the points p(2,0,0) and q(6,2,-2). The examples in my book make no sense and i don't understand cheggs method. I know that r=(1-t)r_0 + t*r_1. I only need help finding the vector equation. Can someone give a step by step explanation?

 

[ineedhelpnow]

I got it

 

[Jameson]

Can you show us your solution anyway so people in the future can reference it? :)

 

[ineedhelpnow]

Only cause u ask :)

r0=<2> and r1=<1/2,1/3,1/4>

r=[(1-t)<2>]+[t<1/2,1/3,1/4>]= <2-t>+<6t,2t,-2t>= <2-4t, 2t' -2t>x=2-4t
y=2t
z=-2t

I'm really sorry but I'm doing it on my tablet and its real hard and tiring to do it in latex.

 

[Jameson]

It's ok. Do you have access to a computer usually? Does your school have computer labs? Just curious.

 

[ineedhelpnow]

I have a computer and laptop at home but I don't like bringing my laptop unless I have to because its heavy.

 

[Jameson]

Meaning you live on campus or not at home and leave the laptop and computer at home? You really go all day with just a tablet? :)

 

[ineedhelpnow]

I live at home. I take my laptop on tuesday and Thursdays because I need it but otherwise I prefer my tablet Mr. Jameson sir

How would I take a desktop computer?!? Drag it by its cord?

 

[Jameson]

I ask because we aren't optimized for tablet use and you yourself admit that it's harder to post certain things from your tablet. When I was in college for my second degree this past semester, I didn't take a tablet or laptop with me for class but I went to the computer lab all the time and posted here on MHB. I think it would be a good idea for you to try to use a laptop or desktop here some more if you can try. :)

Both of you, ineedhelpnow and Mr. Jameson, may I so kindly suggest the http://mathhelpboards.com/chat-room-9/new-hope-talk-spam-episode-2-a-3316.html for off-topic conversations. (Giggle)

Jameson, please don't ban me. (Crying)

I'm kidding. (Rofl)

Well obviously. How else?

I'm going to delete this thread in a bit so it's not important.

why is this your favorite thing to use randomly?

We haven't had users here on tablets as their main device and it leads to some noticeable problems and issues. I am trying to figure out a way that we can all follow our guidelines for posting and not lose convenience. :)

 

[Dethrone]

Hm, is there no way to use LaTeX on a mobile device or tablet?

If you're referring to why I use spoilers, I have no idea. I think I use it to add comments that don't add to the post, but can be relevant?

Not sure what you mean, LaTeX displays fine for me on my mobile. I've never tried posting anything from it, mainly because using a mobile keyboard drives me up the wall, but I don't see why it wouldn't work given LaTeX is just typeset text.

 

[Dethrone]

I guess it works for mobile devices then. So I presume that only tablets don't work well with $\LaTeX$ (Wondering)

I use my tablet and $\displaystyle \begin{align*} \LaTeX \end{align*}$ works fine...

 

[Dethrone]

Oh, haha. I read back and it seemed that $\LaTeX$ works, but it's just cumbersome. Neeevvermind. (Headbang)

 

[ineedhelpnow]

@Jameson yeah its ok that you asked. i use the actually website on my tablet and since everything is so small i tend to tap the wrong things when doing latex and it gets confusing.
