Explanation Approach: If u = 〈 a , b 〉 , v = 〈 c , d 〉 are vectors , then the dot product of u and v is denoted by u ⋅ v , and defined by u ⋅ v = a c + b d . The projection of u into v is the vector proj v u is given by, proj v u = ( u ⋅ v | v | 2 ) v The magnitude of the vector v is given as, | v | = | 〈 a , b 〉 | = a 2 + b 2 Calculation: Consider the vectors u = 〈 x 1 , y 1 〉 and v = 〈 x 2 , y 2 〉 . Consider, proj v u = ( u ⋅ v | v | 2 ) v = [ 〈 x 1 , y 1 〉 ⋅ 〈 x 2 , y 2 〉 x 2 2 + y 2 2 ] 〈 x 2 , y 2 〉 = [ 〈 x 1 x 2 + y 1 y 2 〉 x 2 2 + y 2 2 ] 〈 x 2 , y 2 〉 = [ 〈 x 1 x 2 2 + x 2 y 1 y 2 x 2 2 + y 2 2 , x 1 x 2 y 2 + y 1 y 2 2 x 2 2 + y 2 2 〉 ] Thus,
