Decompose the vector w into a sum of its vectors in its parallel and perpendicular components. The vector w is described as 3 in the x direction and -4 in the y direction. The parallel component of the x vector should be in the direction of the vector u and the perpendicular component of vector w is perpendicular to vector u. The vector u is described as 1 in the x direction and 2 in the y direction.
