(a) Explain what is meant by resolving a vector into rectangular components.
(b) A vector of magnitude V makes an angle θ with the positive x-axis. Derive expressions for its rectangular components Vx and Vy in terms of V and θ.
(c) Using your result from part (b), obtain an expression for the magnitude V of the vector in terms of its components.
(d) Discuss how the algebraic signs of Vx and Vy change when the vector lies in the second and third quadrants of the Cartesian plane.
