I'm not sure if it's because you don't likle the anachronism "feel" to using a calculator or if it's only because you don't like calculators, but im quite sure calculators did exist during ww2 (Can someone confirm/disprove this?). Anyways, the only thing youd have to use it for is Sine, cosine and tangent, THAT has been along for centuries. I don't know why the clever german captains should not take advantage of it.




p.s. I'm working on a way to use this method on the move. Maybe some of you could help me, I looking for an online calculator that would allow me to solve a function. Something like (A+B=x, B+C=y+2, C+D=2x-y ....) Anybody know of something i could use to solve that?

Trigonometric functions yes, but then most commonly in the form of look up tables as far as I know. Unfortunatly I have trouble as it is to keep the plotting speedy enough to be usefull, so thats certainly not for me.

But that's the beauty of it all, you don't have to plot anything (usually i love to plot but i have been frustrated by near misses so often that i gave it up). Of course if your really visual you have to plot, but not if you can pictrure yourself the situation. I havent tried it yet, but this method is probably great for late war-submerged attack ( with the sonar replacing the watchman)

calculators did not exist as we´ve got them today. they had small tables you could move sideways against each other, works pretty good and if you got enough practice it is fast enough.
i build a small html to show you what i meant with the dynamic geometry. scroll down to select the range etc.
its not very exact in html-modus. the version edited in the programm is already pretty good.

sorry, it needs a java applet, i hope it works on your pcs.
here is a screen too:

I'm afraid I'm mathematically retentive

Welcome aboard matey

Hummmmm, I can't blame you guys for being over-polite and i'm happy you are, but you seem to be more happy to wish me luck aboard than to discuss this new method, that would make me happy(i worked really hard on this). Have any of you guys tried it? Anyone having problems with it? Simply can't understand it? Or do you have Suggestions to make it easier/more accurate? Or, do most of you use automatic tdc?

I loved making this thing and im currently working on a way to use it while on the move, but if theres no interst in it and your not even thinking about using it, i wont go through all the work. I'm not complainning here i'm just wondering if your posting here cause your so used to watching the forums and posting that its like a reflex, or if you actually read whats written. Anyways i'm on board, might as well give my two cents.

Pray God, but keep swimming.

Your method seems fine. I haven't tried it but I will give it a shot at some point and come back to you. As far as your explanations it doesn't seem too complex, although I can understand people getting a bit scared about the trigonometry (not that it's difficult but people are affraid of numbers and functions).

Most people do play on auto targeting as it's faster and simple. There are some who play with manual but I don't know how many they are.

Anyhow welcome and enjoy your stay

Im sure this is an excellent method, but im not very good in such mathematics...

You're not the only one Seth. I'm sure most of my students will find it 'overwhelming' and it's really simple
