EQUATION: https://wiki.eveonline.com/wikiEN/images/a/aa/ChanceToHitv2.png


chance to hit= 0
transversal speed= X
range to target= 12000m
tracking speed= 0.7
turret signature resolution= 40m
target signature radius= 110m
turret optimat range= 12000m
turret falloff= 4000m


I want to know the transversal speed X


Can anyone solve this for me please?

you can't actually plug in 0, as you always have a /tiny/ chance to hit.

Woo! CSM XI!

I'm not sure if this is supposed to be a joke or you are just trolling, but there is no solution.

Like Steve pointed out you can't have a chance to hit of 0.
With your chance to hit being 0, this makes the equation: 0=0.5^(lots of stuff including your X)
There is no possible exponent for 0.5 that will give you 0.

Alright..

What about we play with 10 as hit chance?

And thanks.

My TI-89 says 42102 for 0.10 (10% chance)
That's if I didn't mistype anything and my assumptions for what units to use were correct

That tracking figure seems a bit high considering all the other stats are consistent with small beams.

Tracking tool confirms this number.

In very rough terms (ignoring the tracking formula) the turrets in question are able to cover approximately 1/9 of a circle's circumferance per second. The circle in question's circumferance is approximately 75km and therefore the target would have to be travelling at approximately 8.5km/sec to outrun the absolute tracking of the gun.

The sig radius/resolution will alter this value but in very rough terms it represents a place to start - is it possible for the target ship to exceed 8.5km/sec? If its top speed is 4km/sec then outpacing the turret tracking will be impossible anyway...

You couldn't use your existing thread on the exact same topic and only plug in the one value that was missing? What?

Well, something like 30 or more would do it. A value that small is usually considered by programmers to be zero and everything stops there: "you miss". I think at 40 you'll have better chances to win the big price lottery than hit the target.

No ****. OP - stop clicking New Topic.

There is already a thread for this. You should know. You started it. You could have just bumped your own thread.

Get your practical computational considerations out of my math!

I'm gonna make this reaaaaal simple.

Either you hit the target...

Or you don't.

So that's a 50% chance of hitting then Blink

if 42 is the answer then we can assume that all other parts of the formula are incorrect

Quote:

chance to hit= 42
transversal speed= 42
range to target= 42m
tracking speed= 42
turret signature resolution= 42m
target signature radius= 42m
turret optimat range= 42m
turret falloff= 42m

thus solving the OPs question

But..bumping is against the rules.... and OP clearly knows the rules, that's why he didn't bump that thread. But then again...

Don't worry, so was Einstein. He actually hired mathematicians to prove his intuitive ideas for him. They were generally way beyond his capacity to prove.
