`veca,vecb,vec c` are mutually perpendicular unit vectors and `vecd` is a unit vector equally inclined to each other of `veca,vecb` and `vec c` at an angle of `60^@` then `|veca+vecb+vec c+vecd|^2=`

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) .

veca and vecb are two unit vectors that are mutually perpendicular. A unit vector that if equally inclined to veca, vecb and veca xxvecb is equal to

veca and vecb are two unit vectors that are mutually perpendicular. A unit vector that if equally inclined to veca, vecb and veca xxvecb is equal to

veca and vecb are two unit vectors that are mutually perpendicular. A unit vector that if equally inclined to veca, vecb and veca xxvecb is equal to

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 .
