Sure, let's find the components, unit vector, and projection of vector u step by step. Step 1: Find the magnitude of vector u (||u||). The magnitude of vector u (||u||) is given by the formula: ||u|| = √(u₁² + u₂²) Given vector u = <3, -1>, the magnitude of u is: ||u|| = √(3² + (-1)²) = √(9 + 1) = √10 ≈ 3.162 Step 2: Find the unit vector of u (u_hat). The unit vector of u (u_hat) is the vector in the same direction as u but with a magnitude of 1. It is obtained by dividing each component of u by its magnitude. u_hat = u / ||u|| Given vector u = <3, -1>, and ||u|| = √10 ≈ 3.162, the unit vector u_hat is: u_hat = <3/√10, -1/√10> ≈ <0.949, -0.316> Step 3: Find the components of vector u (u_parallel and u_perpendicular). To find the components of vector u, we need a reference vector v that is parallel to u. We'll use vector v = <1, 2> for this purpose. The parallel component of u (u_parallel) with respect to v is given by the formula: u_parallel = (u · v_hat) * v_hat where v_hat is the unit vector of v. First, find v_hat (the unit vector of v): v_hat = v / ||v|| Given vector v = <1, 2> and ||v|| = √(1² + 2²) = √5 ≈ 2.236 v_hat = <1/√5, 2/√5> ≈ <0.447, 0.894> Now, find u_parallel: u_parallel = (u · v_hat) * v_hat u_parallel = (<3, -1> · <0.447, 0.894>) * <0.447, 0.894> u_parallel = (1.341 - 0.894) * <0.447, 0.894> u_parallel = 0.447 * <0.447, 0.894> u_parallel = <0.2, 0.4> The perpendicular component of u (u_perpendicular) with respect to v is given by the formula: u_perpendicular = u - u_parallel u_perpendicular = <3, -1> - <0.2, 0.4> u_perpendicular = <3 - 0.2, -1 - 0.4> u_perpendicular = <2.8, -1.4> Step 4: Find the projection of u onto v (proj_u_v). The projection of u onto v (proj_u_v) is the vector that represents the component of u in the direction of v. It is equal to u_parallel. proj_u_v = u_parallel = <0.2, 0.4> Summary: Magnitude of u (||u||) ≈ 3.162 Unit vector of u (u_hat) ≈ <0.949, -0.316> Parallel component of u (u_parallel) ≈ <0.2, 0.4> Perpendicular component of u (u_perpendicular) ≈ <2.8, -1.4> Projection of u onto v (proj_u_v) ≈ <0.2, 0.4>
