Angle between vectors `vec a and vec b` where `vec a,vec b and vec c` are unit vectors satisfying `vec a +vec b + sqrt3 vec c = 0`

Angle between the vectors vec a and vec b , where vec a, vec b and vec c are unit vectors satisfying vec a + vec b + sqrt3 vec c = vec 0 is

If vec a and vec b are unit vectors find the angle between vec a+vec b and vec a-vec b

If vec a and vec b are unit vectors |vec a xx vec b| =1 then the angle between vec a and vec b is

The vectors vec a and vec b are not perpendicular and vec c and vec d are two vectors satisfying : vec b""xxvec c""= vec b"" xxvec d"",vec a * vec d=0 . Then the vector vec d is equal to : (1) vec b-(( vec bdot vec c)/( vec adot vec d)) vec c (2) vec c+(( vec adot vec c)/( vec adot vec b)) vec b (3) vec b+(( vec bdot vec c)/( vec adot vec b)) vec c (4) vec c-(( vec adot vec c)/( vec adot vec b)) vec b

The vectors vec a and vec b are not perpendicular and vec c and vec d are two vectors satisfying : vec b""xxvec c""= vec b"" xxvec d"",vec a * vec d=0 . Then the vector vec d is equal to : (1) vec b-(( vec bdot vec c)/( vec adot vec d)) vec c (2) vec c+(( vec adot vec c)/( vec adot vec b)) vec b (3) vec b+(( vec bdot vec c)/( vec adot vec b)) vec c (4) vec c-(( vec adot vec c)/( vec adot vec b)) vec b

If two out of the three vectors vec a, vec b, vec c are unit vectors, vec a + vec b + vec c = 0 and 2(vec a . vec b + vec b . vec c + vec a . vec c)+3 =0 , then the third vector of length

If three unit vectors vec a,vec b, and vec c satisfy vec a+vec b+vec c=0, then find the angle between vec a and vec b

Let the vectors vec a and vec b be such that |vec a| = 3 and |vec b| = sqrt2/3 , then vec a xx vec b is a unit vector, if the angle between vec a and vec b is

Let vec a,vec b,vec c are the three vectors such that |vec a|=|vec b|=|vec c|=2 and angle between vec a and vec b is (pi)/(3),vec b and vec c and (pi)/(3) and vec a and vec c(pi)/(3). If vec a,vec b and vec c are sides of parallelogram
