if `veca, vecb and vecc` are there mutually perpendicular unit vectors and `veca` ia a unit vector make equal angles which `veca, vecb and vecc` then find the value of ` |veca+ vecb + vecc + vecd|^2`

If veca,vecb and vecc are three mutually perpendicular unit vectors and vecd is a unit vector which makes equal angal with veca,vecb and vecc , then find the value of |veca+vecb+vecc+vecd|^(2) .

If veca,vecb and vecc are three mutually perpendicular unit vectors and vecd is a unit vector which makes equal angal with veca,vecb and vecc , then find the value of |veca+vecb+vecc+vecd|^(2) .

Statement 1: veca, vecb and vecc arwe three mutually perpendicular unit vectors and vecd is a vector such that veca, vecb, vecc and vecd are non- coplanar. If [vecd vecb vecc] = [vecdvecavecb] = [vecdvecc veca] = 1, " then " vecd= veca+vecb+vecc Statement 2: [vecd vecb vecc] = [vecd veca vecb] = [vecdveccveca] Rightarrow vecd is equally inclined to veca, vecb and vecc .

If veca, vecb, vecc are three non-coplanar mutually perpendicular unit vectors, then [(veca, vecb, vecc)] is

If veca,vecb,vecc are mutually perpendicular vectors of equal magnitude show that veca+vecb+vecc is equally inclined to veca, vecb and vecc

if veca,vecb and vecc are mutally perpendicular vectors of equal magnitudes, then find the angle between vectors and veca+ vecb+vecc .

If veca, vecb, vecc are unit vectors such that veca. Vecb =0 = veca.vecc and the angle between vecb and vecc is pi/3 , then find the value of |veca xx vecb -veca xx vecc|

Let veca, vecb, vecc be three unit vectors and veca.vecb=veca.vecc=0 . If the angle between vecb and vecc is pi/3 then find the value of |[veca vecb vecc]|

Let veca, vecb, vecc be three unit vectors and veca.vecb=veca.vecc=0 . If the angle between vecb and vecc is pi/3 then find the value of |[veca vecb vecc]|
