Finding the components from the magnitude and angleGiven that the straightline distance from Los Angeles to Las Vegas is 370 km, and that the angle θ in the figure is 38 °, how can the x and y components of the Δr vector be found? The sine and cosine of θ relate the given information to the information we wish to find:
Solving for the unknowns gives
