Best ResponseYou've already chosen the best response.1dear for writing the plane we need a point and a line which cross the plane am i right ?

Best ResponseYou've already chosen the best response.1u 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?

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

Roya

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

Best ResponseYou've already chosen the best response.1in 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

ajprincess

Best ResponseYou've already chosen the best response.1i tried bt nt getting t. can u plzz help me dear?

Best ResponseYou've already chosen the best response.1u know , i'm not sure about the solution .

Roya

Best ResponseYou've already chosen the best response.1i'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 ?

Best ResponseYou've already chosen the best response.1dear is it a special tetrahedron ? i mean symmetric or ortoghonal ?

Roya

Best ResponseYou've already chosen the best response.0Here is how to write the planes of the tetrahedron using vecors I think.

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

ajprincess

Best ResponseYou've already chosen the best response.1I 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.

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

Best ResponseYou've already chosen the best response.1I 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.

Best ResponseYou've already chosen the best response.1it's k. I got an answer. If I make an adjustment to that I am getting it right. Bt am nt sure if I am right. Anyways thanxxx a lot for coming to the rescue.
