Topic: passing vectors to a function

I would like to book passage on the next trip please.

Great job Kerry.

hi

is there any reason why i would express location and angles with vectors rather than coordinates?

and i notice the Line command is represented only by vectors , why?

[Kerry]

yes.
UCS.
Adding vectors is quicker than the polar function.

90% (or even more) you'd draw by using vectors. It's extremely seldom that you'd calculate the exact coordinate on all the points of linework. At worst you'd think of the start position of a line (ITO the full coordinate), then the vector for its 2nd point (i.e. how long and in what direction for polar vectors, and how much X and Y and Z to "move" for coordinate vector). Only for things where the coordinates are already calculated for you would you prefer to fill in the XYZ as a full coordinate (e.g. the X/Y's of property lines).

Think of this as using the @ prefix to the line command as opposed to using the # prefix when typing in the X,Y,Z values. I.e. how far from the previous point instead of at which global point irrespective of what's gone before it.

Speaking of Vector Trips, today I was reminded of this:

Vectors in Linear Algebra
1.1 Opening Remarks
1.1.1 Take Off
Co-Pilot Roger Murdock (to Captain Clarence Oveur):  We have clearance, Clarence.
Captain Oveur:                                                             Roger, Roger. What’s our vector, Victor?”

Hays, Julie Hagerty, Leslie Nielsen, Robert Stack, Lloyd Bridges, Peter Graves,
Kareem Abdul-Jabbar, and Lorna Patterson. Paramount Pictures, 1980. Film.

From the same movie source, for perspective:
Rumack:      I won't deceive you, Mr. Striker. We're running out of time.
Ted Striker: Surely there must be something you can do.
Rumack:      I'm doing everything I can... and stop calling me Shirley!


Operator: [Captain Oveur is on the phone with the Mayo Clinic] Excuse me, Captain Oveur, but I have an emergency call on line five from a Mr. Hamm.
Captain Oveur: Alright, give me a Hamm on five, hold the Mayo.
