Best ResponseYou've already chosen the best response.1I was thinking that the normal vector was [8,0] and that the direction vector was [0,8] and the position vector was [8,0].

Best ResponseYou've already chosen the best response.1My final answer was [x,y]=[8,0]+t[0,8]. But I am wrong.

Best ResponseYou've already chosen the best response.0I'm still searching, but can you apply something like this? http://www.blurtit.com/q1900770.html (google'd) I don't have your book... is it a calc book?

Best ResponseYou've already chosen the best response.1I dunno. Yes, it is a Calculus and Vectors book.

Best ResponseYou've already chosen the best response.2why is your answer wrong?

IsTim

Best ResponseYou've already chosen the best response.1The actual answer is [x,y]=[8,2]+t[0,1].

IsTim

Best ResponseYou've already chosen the best response.1I've doublechecked to make sure the facts are right.

Best ResponseYou've already chosen the best response.2the 8 isn't necessary but acceptable.... both your eq. and answer equation are acceptable...

Best ResponseYou've already chosen the best response.2direction vector can be any vertical vector... starting point postion vector can refer to any point on line Infinite acceptable answers.

Best ResponseYou've already chosen the best response.1Like, I know that [8,0] can be anything, but my answer still isn't right in terms of t[0,1].

Best ResponseYou've already chosen the best response.0Sorry IsTim, I've searched through my calc book and solutions manual, but I guess 89 years is too long to remember enough of this. Hope PaxPolaris is able to help you understand. :)

Best ResponseYou've already chosen the best response.2direction vector can be any vertical vector ... [0,1] and [0,8] are both parallel to the line so both are acceptable ... any vector [0,C] is acceptable.

Best ResponseYou've already chosen the best response.1Wait, you're sure you're not talking about position vector?

Best ResponseYou've already chosen the best response.2no, we're done with that...??

IsTim

Best ResponseYou've already chosen the best response.1I don't know, they way you describe the direction vector sounds like the way my teacher described a position vector.

Best ResponseYou've already chosen the best response.2Position Vector: of any 1 point on the line Direction Vector: any vector parallel to the line

Best ResponseYou've already chosen the best response.1But then what's the constant?

PaxPolaris

Best ResponseYou've already chosen the best response.2the slope of the direction vector is constant ... the length of the direction vector is irrelevant

IsTim

Best ResponseYou've already chosen the best response.1Ok. I'll just leave this question as is for now. Thanks for the help anyways, PAx.

Best ResponseYou've already chosen the best response.2eg. if your direction vector is [1,2]: it can also be [2,4] , [3,6], [5,10]....[n,2n] preferably you'd use the simplest form i.e. [1,2] or in your case [0,1] instead of [0,8] http://www.netcomuk.co.uk/~jenolive/vect3.html

Best ResponseYou've already chosen the best response.0Evidently, my book wasn't good enough to help. I was reading through some of this, after p.4, that seemed that it might help some. http://mysite.science.uottawa.ca/vbozi013/mat1339/ch08.pdf PaxPolaris' site is good too :)
