To find the cross product of vectors ( \mathbf{a} = \langle 1, 2, -4 \rangle ) and ( \mathbf{b} = \langle -1, -1, 2 \rangle ), we use the formula ( \mathbf{a} \times \mathbf{b} = \langle a_2b_3 - a_3b_2, a_3b_1 - a_1b_3, a_1b_2 - a_2b_1 \rangle ). Substituting the values, we get ( \mathbf{a} \times \mathbf{b} = \langle 6, -2, -1 \rangle ).

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.

- Can object have a varying speed if its velocity is constant? Can it have varying velocity if its speed is constant? If yes, give examples in each case.
- What is the cross product of #(14i - 7j - 7k)# and #(-5i + 12j + 2 k)#?
- Objects A and B are at the origin. If object A moves to #(-7 ,3 )# and object B moves to #(-6 ,2 )# over #3 s#, what is the relative velocity of object B from the perspective of object A? Assume that all units are denominated in meters.
- A projectile is shot from the ground at an angle of #pi/6 # and a speed of #15 m/s#. Factoring in both horizontal and vertical movement, what will the projectile's distance from the starting point be when it reaches its maximum height?
- A projectile is shot from the ground at an angle of #pi/8 # and a speed of #7 /12 m/s#. Factoring in both horizontal and vertical movement, what will the projectile's distance from the starting point be when it reaches its maximum height?
