[FT] Vector Movement Cheat Sheet

I got this message from my opponent in a recent game:

> MB 4, RP 5, to heading 11. This leaves every ship in my fleet with

I made a chart with Facings as the columns and Thrust as the rows. I tried
copying it into this message from MS Excel but it isn't properly spaced and
will be easier, I think, to make your own (although I'll eventually make a
table in HTML). Each cell has a formula to calculate the change in X (or Y)
position based on the amount of thrust you're using and the heading. X =
Thrust * sin(Heading * 30 degrees), Y the same except cosine instead of sine.
If you're using Excel, you have to convert from radians to degrees,
so you'd have sin(Heading*30*PI()/180).

Using this chart, we see that the first vector mentioned yields (+18,
+0),
the second (+0, -2), and the third (+3.46, -2).  Adding these together,
we
find his endpoints are (+21.46, +0) from his initial position.  This is
quick and easy (otherwise I couldn't do it), does not demand a computer (eg if
you're working out your positions on the bus, at work, etc.), and is more
accurate than plotting on graph paper.

Hope this helps.
