Resolve the following vectors into components:

(a) The vector [math] in 2-space of length 3 pointing up at an angle of [math] measured from the positive [math]-axis.
[math] [math] + [math]

(b) The vector [math] in 3-space of length 1 lying in the [math]-plane pointing upward at an angle of [math] measured from the positive [math]-axis.
[math] [math] + [math] + [math]
