A = i-2j-3k এবং B = 4i - 2j + 6k দুটি ভেক্টর দেওয়া আছে। X-অক্ষের সাথে (A + B) দ্বারা তৈরি কোণ হল...

Given two vectors vec(A) = -hat(i) + 2hat(j) - 3hat(k) and vec(B) = 4hat(i) - 2hat(j) + 6hat(k) . The angle made by (A+B) with x-axis is :

If bara = 2i + 3j - k , barb = - i + 2 j - 4k and barc = i + j + k . then (a xx b) · ( a xx c)

If vec(A) = 2 I + j - k , vec(B) = I + 2 j + 3 k , and vec(C ) = 6 i - 2 j - 6 k ,then the angle between (vec(A) + vec(B)) and vec(C ) will be

Given two vectors A=i-2j-3k and B=4i-2j+6k .The angle made by A+ B with the x axis is xy degrees then x+y=

2i · (j xx k) - 3j · (i xx k) - 4k · (i xx j) =

If a=3i+2j+k, b=5i-j+2k" and "c=i+j+k , find [a b c]

if vec a=2i+j+3k and vec b=3i+5j-2k then |a xx b|
