(w • u) x v or (wxu) •v (2 park) The reason this one cannot be done is that the dot product always gives a scalar quanity and is a vector and you cannot get the cross product of a scalar and vector, In 3-space if a b = 0 and 5 c = 0, does that mean a &c are collinear? Explain Fully. and are collinear since the dot product are equal to one another. X (4 marks) 2 Explain clearly why (a+b). (axb)=0 will always equal 0.
