When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A projectile is shot at a velocity of # 5 m/s# and an angle of #pi/8 #. What is the projectile's peak height?
- Objects A and B are at the origin. If object A moves to #(6 ,7 )# and object B moves to #(-1 ,3 )# over #4 s#, what is the relative velocity of object B from the perspective of object A?
- What is the cross product of #[3, 1, -4]# and #[2, 6, -1] #?
- What is the unit vector that is normal to the plane containing #(3i + 4j - k)# and #(2i+ j - 3k)#?
- A projectile is shot from the ground at an angle of #pi/8 # and a speed of #16 m/s#. When the projectile is at its maximum height, what will its distance from the starting point be?
