--- Quote from: immortal on May 11, 2010, 08:20:02 am ---I think u missed out something..
anyway da first part cn b done using nid404's method

ii>da ratio of i:k  =1:2
   AB~(12-9)i+(-4-2)j+(-5-q)k
          3i-6j+(-5-q)k
  
Tere4     using   1:2
                 -5-q=6
               q=-11
Now its also possible 2 find p
As da ratio is 3:6  =1:2
p=-2/3 (as p is a negative constant)

--- End quote ---

thanks..could u please tell me from where did u get the ratio and 6??

immortal:
1/3i + pj +2/3k
1/3:2/3
1:2(ignoring j)
3i-6j+(-5-q)k , as i=3    k=3*2(ratio)=6

ny:
okay! thank you soo much,
yeah,my p1 is tmrow.
all the best!
