###### Question details

1). Explain the equivalence of the expressions u x v=u1v1 + u2v2 and u x v=/u//v/cos(θ) 2). Draw a picture that demonstrates what the orthogonal projection of u onto v and the scalar projectionof u onto v is. (PLEASE WXPLAIN THESE TWO QUESTION STEP BY STEP AND DRAW A PICTURE). WILL RATE!
