The angle between vec(a) and vec(b) " is " 0^(@) then angle between 2 vec(a) and -3 vec(b) is
Find the angle between two vectors vec(A)=2i+j-k and vec(B)=i-k .
Let vec(a)= 2vec(i) + vec(j)-2vec(k), vec(b)= vec(i) + vec(j) " if " vec(c ) is a vector such that vec(a).vec(c )= |vec(c )|, |vec( c)- vec(a)|= 2 sqrt2 and the angle between vec(a) xx vec(b) and vec(c ) " is " 30^(@) , then find |(vec(a) xx vec(b)) xx vec( c)|
