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 angle 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 angle 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) .

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 there mutually perpendicular unit vectors and veca ia a unit vector then find the value of |2veca+ vecb + vecc |^2

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

If veca, vecb, vecc are three mutually perpendicular unit vectors then |veca+vecb+vecc| is

If veca,vecb,vecc are mutually perpendicular unit vectors then |veca+vecb+vecc| is equal to

If veca,vecb,vecc are three mutually perpendicular unit vectors, then prove that abs(veca+vecb+vecc)=sqrt3

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 .
