There are a couple of reasons I included the vector analysis in the tutorial movie:
1. I love elegant solutions that can be verified by inspection. Vector analysis is fun, even for normally math-challenged people.
2. Respect for Nisgeis, who suggested this tactic to begin with and didn't understand my explanation of the Dick O'Kane attack. I thought "What if there are more like him who are having problems with the TDC method but could use the vector analysis method?" They deserve help too.
3. Although I believe the TDC method is less prone to error than the vector analysis method, it is true that one method can be used to verify the other.
4. While you are in port, you go to the local watering hole. Inside is this gorgeous piece of womanflesh. You approach her and find out she's some kind of philologist or something and you can't seem to make any kind of connection. You merely whip out a napkin and draw the vector analysis of your last torpedo attack. SHE'S YOURS PAL!!! Take her home.:rotfl:
Aaronblood, I'm a promoter of ideas. Some of them are irrelevent, such as what the "s" in S-Boat stands for. Some, such as the vector analysis, may be good only for understanding the underlying concept behind the attack. The vector analysis can also be used to show why in this type of solution the range doesn't matter. What happens to the angles when you double all the measurements? (they remain the same). And vector analysis is just plain fun. Yeah, I'm crazy as you are!
