WebWe also want the vector v to have length one, i.e. v =1. In total, we get two constraints on v: (i) 3x + 4y = 5/2 (from your u, the dot-product formula, and the above equation) (ii) x^2 + y^2 = 1 (since the length (the square root of this) should be 1) Right. Now we have to solve this for x and y. Equation (i) gives us that x = 5/6 - 4y/3 WebWith the two kinds of multiplication of vectos, the projection of one to the other is included. Taking, for example, two parallel vectors: the dot product will result in cos (0)=1 and the multiplication of the vector lengths, whereas the cross product will produce sin (0)=0 and zooms down all majesty of the vectors to zero.
