Zero gyro shooting
This is the quick and not–so–dirty method I use. I've found it quite handy when the tactical situation gets chaotic.
Plug the formula into your fx-5000F or smart phone and Bob’s your uncle. Heck, grab a pack of Lucky’s, a cup a joe, whip out the old slip-stick and do it old school! Don't let the trigonometry intimidate you. After a couple of patrols you may find yourself solving this in your head. I hope you find it useful. |

I see someone else has been putting their high school geometry to good use. |

There are some interesting hacks one may use to eliminate the above trig functions altogether. But seeing as this formula is only executed a couple of times per hour, the effort to include them far outweighed their utility.

Hey Dorjun. Do you know if the "asin" function is the same as "arcsin"? I'm trying to replicate your formula in a smartphone calculator and it only has an asin function. I'm not getting the correct solution in my tests and I'm wondering if this is why. Math was never my strength.
EDIT: another question... I am building my formula using letters for my variables. V for ship velocity, T for Torp speed. This seems to work fine but for track angle do I need to attach some trig function so the calculator knows its an angle and not a quantity? I've just been using "A" for track angle but I don't know if the formula is understanding this as an angle. Is this my problem by chance?
