Let `bar(a),bar(b)` be vectors `|bar(a)|=|bar(b)|=5` and `(bar(a),bar(b))=45^(@)`. Find area of `Delta` having `bar(a)-2bar(b),3bar(a)+2bar(b)` as two of its sides.

bar(a),bar(b) are such that |bar(a)|=sqrt(3),|bar(b)|=2 and (bar(a),bar(b))=(pi)/(3). Then the area of the triangle with adjacent sides bar(a)+2bar(b) and 2bar(a)+bar(b) is

bar(a),bar(b) are such that |bar(a)|=sqrt(3),|bar(b)|=2 and (bar(a),bar(b))=(pi)/(2). Then the area of the triangle with adjacent sides bar(a)+2bar(b) and 2bar(a)+bar(b) is

If |bar(a)+bar(b)|<|bar(a)-bar(b)| then (bar(a),bar(b)) is

If |bar(a)|=3,|bar(b)|=4 and |bar(a)+bar(b)|=5, then |bar(a)-bar(b)| is equal to

If |bar(a)|=3,|bar(b)|=4,|bar(a)-bar(b)|=5 then |bar(a)+bar(b)|=...

Let bar(a),b,bar(c) are three vectors such that , |bar(a)|=|bar(b)|=|bar(c)|=2 and (bar(a),bar(b))=(pi)/(3)=(bar(b),bar(c))=(bar(c),bar(a)) The volume of the parallelepiped whose adjacent edges are 2bar(a),3bar(b),4bar(c)

If |bar(a)|=|bar(b)|=1 and |bar(a)timesbar(b)|=bar(a)*bar(b) , then |bar(a)+bar(b)|^(2)=

If |bar(a)|=|bar(b)|=|bar(c)|=2 and bar(a).bar(b)=bar(b).bar(c)=bar(c).bar(a)=2 then [bar(a) bar(b) bar(c)] equal to

If bar(a),bar(b),bar(c) are three non zero vectors,then bar(a).bar(b)=bar(a).bar(c)rArr

If |bar(a)| =2 and |bar(b)|=3 and bar(a).bar(b)=0 then |(bar(a)times(bar(a)times(bar(a)times(bar(a)timesbar(b)))))|-
