How can vectors be represented?
Adrian AyalaLet us have a physical quantity with a magnitude A.
If it is a vector , we can write it in bold A to express a magnitude leading in a certain direction.

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.

- What is the cross product of #<4 , 5 ,-9 ># and #<4, 1 ,-2 >#?
- A projectile is shot from the ground at an angle of #(5 pi)/12 # and a speed of #7 /3 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 basketball player is trying to make a half-court jump shot and releases the ball at the height of the basket. Assuming that the ball is launched at 51.0°, 14.0m from the basket, what speed must the player give the ball?
- What is the unit vector that is orthogonal to the plane containing # (32i-38j-12k) # and # (41j+31k) #?
- Objects A and B are at the origin. If object A moves to #(-8 ,-5 )# and object B moves to #(-1 ,4 )# 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.
