Let the angle between two non - zero vectors `vec(A)` and `vec(B)` be `120^(@)`and its resultant be `vec( C)`.

Let the angle between two nonzero vectors vec(A) and vec(B) be 120^(@) and its resultant be vec(C) .

If the angle between two vectors vec(a) and vec(b) is zero, then :

If θ is the angle between two non-zero vectors vec a and vec b , then write down the value of sin θ .

Resultant of three non-coplanar non-zero vectors vec a , vec b and vec c

If vec a and vec b are two non -zero vectors, then (vec a + vec b) .(vec a - vec b) is equal to

Show that |vec(a)|vec(b)-|vec(b)|vec(a) , for any two non - zero vectors vec(a) and vec(b) .

vec(a),vec(b) and vec( c ) are non zero vectors. (vec(a)xx vec(b))xx vec( c )=(1)/(3)|vec(b)||vec( c )|vec(a) . If the acute angle between the vectors vec(b) and vec( c ) is theta then sin theta = ……………

Let veca,vecb,vecc be three non-zero vectors such that vec(c) is a unit vector perpendicular to both vec(a)andvec(c). If the angle between vec(a)andvec(c)" is "(pi)/(6)," show that "[vec(a),vec(b),vec(c)]^(2)=(1)/(4)absvec(a)^(2)absvec(b)^(2).

Let vec a,vec b,vec c are three non-zero vectors and vec b is neither perpendicular to vec a nor to vec c and " (vec a timesvec b)timesvec c=vec a times(vec b timesvec c) .Then the angle between vec a and vec c is:

Let vec a,vec b,vec c be three non-zero vectors such that vec c is a unit vector perpendicular to both vec a and vec b. If the between vec a and vec b is pi/6 prove that [vec avec bvec c]^(2)=(1)/(4)|vec a|^(2)|vec b|^(2)
