Find `|veca-vecb|`, if two vectors `veca and vecb` are such that `|veca|=2,|vecb|=3 and veca.vecb=4`.

Find |veca-vecb| , if two vector veca and vecb are such that |veca|=4,|vecb|=5 and veca.vecb=3

For any two vectors veca and vecb prove that |veca.vecb|<=|veca||vecb|

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

For any two vectors veca and vecb prove that |veca+vecb|lt+|veca|+|vecb|

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

Let veca and vecb are vectors such that |veca|=2, |vecb|=3 and veca. vecb=4 . If vecc=(3veca xx vecb)-4vecb , then |vecc| is equal to

If veca and vecb are non - zero vectors such that |veca + vecb| = |veca - 2vecb| then

veca and vecb are two vectors such that |veca|=1 ,|vecb|=4 and veca. Vecb =2 . If vecc = (2vecaxx vecb) - 3vecb then find angle between vecb and vecc .

If |veca|=8,|vecb| = 3 and |veca xxvecb|=12 , find veca.vecb
