If bar(a), bar(b) are two non collinear vectors, then bar(r)=sbar(a)+tbar(b) represents

If bar(a) and bar(b) are two non-zero, non-collinear vectors such that xbar(a)+ybar(b)=bar(0) then

Suppose bar(a), bar(b), bar(c) be three unit vectors such that |bar(a)-bar(b)|^(2)+|bar(b)-bar(c)|^(2)+|bar(c)-bar(a)|^(2) is equal to 3 . If bar(a), bar(b), bar(c) are equally inclined to each other at an angle:

bar(a),bar(b) and bar( c ) are unit vectors. The value of |bar(a)-bar(b)|^(2)+|bar(b)-bar( c )|^(2)+|bar( c )-bar(a)|^(2) is not expected ………………

If bar(a),bar(b) aretwo unit vectors such that |bar(a)xxbar(b)|=2 then the value of [bar(a)bar(b)bar(a)xxbar(b)] is

Let bar(a),bar(b) be two non-collinear unit vectors, if bar(alpha) = bar(a) -(bar(a).bar(b))bar(b) and bar(beta) = bar(a) xx bar(b), then show that |bar(beta)| = |bar(alpha)| .

If bar(a),bar(b),bar(c) are non-zero,non-coplanar vectors then {bar(a)times(bar(b)+bar(c))}times{bar(b)times(bar(c)-bar(a))} is collinear with the vector

If bar(a) and bar(b) are two vectors perpendicular each other, prove that (bar(a) + bar(b))^(2) = (bar(a) - bar(b))^(2)

If bar(a) , bar(b) are non-zero vectors such that |bar(a)+bar(b)|^2 = |bar(a)|^(2)+ |bar(b)|^(2) , then find the angle between bar(a) , bar(b) .
