Let the direction of the vector be represented by the angle θ, which is measured counterclockwise from the positive x-axis. The x-component of the vector is given by: Ax = |A| cos(θ) The y-component of the vector is given by: Ay = |A| sin(θ) The vector can now be represented as a list of numbers: A = (Ax, Ay) For example, if a vector has a magnitude of 5 units and a direction of 30° counterclockwise from the positive x-axis, its components would be: Ax = 5 cos(30°) ≈ 4.33 units Ay = 5 sin(30°) ≈ 2.50 units The vector can now be written as A = (4.33, 2.50) source
