यदि दो सदिशों `vec(a)` और `vec(b)` के बीच का कोण `theta` है तो `vec(a) . vec(b) ge 0 ` होगा। यदि -

If theta is the angle between two vectors vec(a) and vec(b) , then vec(a).vec(b) ge 0 only when

If theta is the angle between two vectors vec(a) and vec(b) , then vec(a).vec(b) ge 0 only when

If vec(a), vec(b) and vec(c) are three vectors such that vec(a) + vec(b) + vec(c) = vec(0) , then prove that vec(a) xx vec(b) = vec(b) xx vec(c) = vec(c) xx vec(a) .

If vec( A) + vec(B) =vec( C ) , and | vec(A)| =2 | vec( B) | and vec( B). vec( C ) = 0 , then

If vec( A) + vec(B) =vec( C ) , and | vec(A)| =2 | vec( B) | and vec( B). vec( C ) = 0 , then

If theta is angle between two vectors vec(a) and vec(b) then vec(a).vec(b)ge 0 only when …….

If |vec(a)+vec(b)|ge|vec(a)-vec(b)| then angle between vec(a) and vec(b) may be

If |vec(a)+vec(b)|ge|vec(a)-vec(b)| then angle between vec(a) and vec(b) may be

If theta be the angle between two vectors vec(a) and vec(b) , then vec(a).vec(b)ge0 only when

If vec(a).vec(b)=0 and vec(a) xx vec(b)=0, " prove that " vec(a)= vec(0) or vec(b)=vec(0) .
