Question

In Problems 59–64, write the vector v in the form ai + bj, given its magnitude || v || and the angle a it makes with the positive x-axis.
59. || v || = 5, a = 60°

60. || v || = 8, a = 45°

61. || v || = 14, a = 120°

62. || v || = 3, a = 240°

63. || v || = 25, a = 330°

64. || v || = 15, a = 315°
