यदि bar(a),bar(b) और bar(c) कोई सदिशहों, तो सिद्ध कीजिए कि bar(a)xx(bar(b)+bar(c))+bar(b)xx(bar(...

If bar(a)+bar(b)+bar(c), then

If bar(a)xxbar(b)=bar(c) and bar(b)xxbar(c)=bar(a), then

[bar(a)" "bar(b)+bar(c)" "bar(a)+bar(b)+bar(c)]=0

bar(a) , bar(b) and bar(c) are three vectors such that bar(a) + bar(b) + bar(c) = bar(0) and |bar(a)| =2, |bar(b)| =3, |bar(c)| =5 ,then bar(a) . bar(b) + bar(b) . bar(c) + bar(c) . bar(a) equals

bar(a),bar(b),bar(c) are three unit vectors such that bar(a)xx(bar(b)xxbar(c))(1)/(2)bar(b), then (bar(a),bar(b))=(bar(a),bar(c))=(bar(b),bar(c)), are non-collinear)

If 4bar(a)+5bar(b)+9bar(c)=bar(0) then (bar(a)xxbar(b))xx[(bar(b)xxbar(c))xx(bar(c)xxbar(a))]=

If bar(a),bar(b),bar(c) are non-coplanar vectors such that then bar(b)xxbar(c)=bar(a),bar(c)xxbar(a)=bar(b) and bar(a)xxbar(b)=bar(c), then |bar(a)+bar(b)+bar(c)|=

If bar(a),bar(b),bar(c) are coplanar then the value of |[bar(a),bar(b),bar(c)],[bar(a)*bar(a),bar(a)*bar(b),bar(a)*bar(c)],[bar(b).bar(a),bar(b)*bar(b),bar(b)*bar(c)]|=

bar(a)xx(bar(b)xxbar(c)) is parallel to bar(b), then

if bar(a),bar(b),bar(c) are any three vectors then prove that [bar(a),bar(b)+bar(c),bar(a)+bar(b)+bar(c)]=0
