dear for writing the plane we need a point and a line which cross the plane am i right ?
 one year ago

ajprincessBest ResponseYou've already chosen the best response.1
u mean for writing the eqn of the plane? bt v can write it if v knw the position vectors of thr three points isnt it?

RoyaBest ResponseYou've already chosen the best response.1
yes so u know out and in multiple .

RoyaBest ResponseYou've already chosen the best response.1
if u multiple out and b and like this for others plane u have the line and u have the point .

i'm not sure i ask a friend for help but what i said is this :
 one year ago

RoyaBest ResponseYou've already chosen the best response.1
in our question we have a b c vectors , for each plane if u cross product both of them u get the line ortoghonal to the plane and u have the point i mean a1 b1 and the other

i tried bt nt getting t. can u plzz help me dear?

u know , i'm not sure about the solution .

RoyaBest ResponseYou've already chosen the best response.1
i's so sri because i can't help u . but think about my idea . what if we suppose our space with 3 vector a b c instead i j k ? could we find out the answer ?

let me try and see.

Here is how to write the planes of the tetrahedron using vecors I think.
 one year ago

ajprincessBest ResponseYou've already chosen the best response.1
I wrote the equations of planes as follows. dw:1337970519951:dwdw:1337970602748:dw
 one year ago

ajprincessBest ResponseYou've already chosen the best response.1
I wrote it so cos the equation of a plane through three points is dw:1337970955268:dw were r is p.v of any point R on the required plane, a,b and c are p.v of the given points A,B, and C.

Am I right @timo86m

timo86mBest ResponseYou've already chosen the best response.0
seems right use it to prove those things it says.

I got the answer for the first part.:0

timo86mBest ResponseYou've already chosen the best response.0
for 1 you can just take vector D to D1 Use vector addition and it will equal RHS

this is a tough one :) lol
 one year ago

ajprincessBest ResponseYou've already chosen the best response.1
I did it in this way. Let the position vector of D1 with respect to D be d1. Since D1 lies in the plane ABdw:1337972129746:dw and since DD1//DKdw:1337972217587:dwdw:1337972258266:dwdw:1337972326958:dwdw:1337972383792:dw Such a lengthy method.
