Evaluate :
`( vecA + vecB ) + ( vecA - vecB )` =

What is the property of two vectores vec A and vec B if: (A) |vecA + vecB|= |vecA - vecB| (b) vecA + vecB = vecA - vecB

If vecA||vecB then vecA xx vecB =……….

For vectors vecA and vecB , (vecA + vecB). (vecA xx vecB) will be :

If vec A . vecB = vecA*vecB , find |vecA - vecB|

Vectors vecA and vecB satisfying the vector equation vecA+ vecB = veca, vecA xx vecB =vecb and vecA.veca=1 . Vectors and vecb are given vectosrs, are

Vectors vecA and vecB satisfying the vector equation vecA+ vecB = veca, vecA xx vecB =vecb and vecA.veca=1 . Vectors and vecb are given vectosrs, are

Let veca , vecb,vecc be three vectors such that veca bot ( vecb + vecc), vecb bot ( vecc + veca) and vecc bot ( veca + vecb) , " if " |veca| =1 , |vecb| =2 , |vecc| =3 , " then " | veca + vecb + vecc| is,

If [ veca vecbvecc]=2 , then find the value of [(veca+2vecb-vecc) (veca - vecb) (veca - vecb-vecc)]

If [ veca vecbvecc]=2 , then find the value of [(veca+2vecb-vecc) (veca - vecb) (veca - vecb-vecc)]
