If the vector `vec(a), vec(b), vec(c)` form the sides BC, CA and AB respectively of a triangle ABC, then

Let vec a,vec b,vec c form sides BC,CA and AB respectively of a triangle ABC then

If the vectors vec(a), vec(b), vec(c ) form the sides vec(BC), vec(CA), vec(AB) respectively of triangle ABC then show that vec(a) xx vec(b) = vec(b)xx vec(c ) = vec(c ) xx vec(a) .

It the vectors vec(a), vec(b) and vec(c) form the sides vec(BC), vec(CA) and vec(AB) respectively of a triangle ABC, then write the value of vec(a) xx vec(c) + vec(b) xx vec(c) .

If the vectors vec(a), vec(b), vec(c ) are represents the sides vec(BC), vec(CA) and vec(AB) respectivley of triangle ABC, then

If D,E,F are the mid points of the side BC,CA and AB respectively of a triangle ABC,write the value of vec AD+vec BE+vec CF

If vec a,vec b,vec c are position vectors of the vertices A,B and C respectively,of a trriangle ABC, write the value of vec AB+vec BC+vec CA

Let D, E and F be the middle points of the sides BC,CA and AB, respectively of a triangle ABC. Then prove that vec AD+vec BE+vec CF=vec 0

If D,E and F are the mid-points of the sides BC, CA and AB respectively of a triangle ABC and lambda is scalar, such that vec(AD) + 2/3vec(BE)+1/3vec(CF)=lambdavec(AC) , then lambda is equal to
