If `bar(a),bar(b),bar(c)` are non-coplanar unit vectors each including the angle of measure `30^(@)` with the other, then find the volume of tetrahedron whose co-terminal edges are `bar(a),bar(b),bar(c)`.

Derive the expression for the volume of the prallelopiped whose coterminus edges are vectors bar(a),bar(b),bar(c) .

If the unit bar(a),bar(b) and bar( c ) are coplanar then …………..

bar(a),bar(b),bar(c ) are three coplanar vectors, If bar(a) is not parallel to bar(b) , Show that

If bar(a),bar(b),bar(c ) are mutually perpendicular unit vectors, then find [bar(a)bar(b)bar(c )]^(2) .

If bara,barb,barc are non-coplanar vectors then [bar(a)+2bar(b)" "bar(a)+bar(c)" "bar(b)]=

If bara,barb,barc are non-coplanar vectors then [bar(a)+2bar(b)" "bar(a)+bar(c)" "bar(b)]=

If bar(a) , bar(b) and bar(a)-sqrt2bar(b) are unit vectors, then what is the angle between bar(a), bar(b) ?

If bar(a),bar(b) and bar(c) are non-coplanar unit vectors such that bar(a)times(bar(b)timesbar(c))=(1)/(sqrt(2))(bar(b)+bar(c)) ],then which of the following statements are correct A. (bar(a),bar(c))=(3 pi)/(4) B. (bar(a),bar(b))=(3 pi)/(4) C. (bar(a),bar(b)+bar(c))=(pi)/(2) D.(bar(b),bar(c))=0
