QUESTION
I have a list of circles (x, y, radius) and a line origin (x, y), I want to be able to determine a line segment that intersects as many circles as possible with one of it's points being the line origin, the line is completely straight. This is all in 2D.
Circles have a fixed radius and can overlap. There is no minimum distance that the line has to intersect with the circle.
An image of what I want:
Psuedocode is fine.
UPDATE:With some help and ideas from the comments and answer(s) I have figured out how to do this, it could probably do with some optimization though.
I have created two codepens, one of them has code that tries to center the angle, but is more resource intensive, and one that doesn't.
No Centering: https://codepen.io/joshiegemfinder/pen/gOXzXOq
With Centering: https://codepen.io/joshiegemfinder/pen/abVGLRJ
I'll write my code examples in javascript, as that's probably the easiest understood language
To find the line segment that intersects the most circles, you have to take the two tangents of each circle (that pass through the line origin) like this:
...ANSWER
Answered 2022-Apr-04 at 06:55As suggested by @Stef, compute the angles (on four quadrants) of all tangents to the circle from the line origin. Tag the angles with +1 and -1 in the trigonometric rotation order, and sort them increasingly. Ignore the circles that surround that origin.
Now form the prefix sum of the ±1 tags and consider the angular interval that yields the largest value.
To get the angles for a circle, compute the polar argument of the center and add plus or minus the half aperture, the sine of which is the ratio of the circle radius over the distance center-origin.

I have a table where i have added 2 nearby locations which i calculated from google map.
Now my query is to get that nearby location with this query
...ANSWER
Answered 2022-Apr-03 at 19:25Using the modern version of distance, you get an result.
But i don't know why you are grouping it
so with your data
Your problem is basically only the decimal column as it cuts out all digits after the 9 th and so the comparison will fail always,
You have two possibilies
Save the data as varchar or double like in the example. or use spatial datatype
where xyou save the point

I was reading the lazy getter example of the Lombok library, but could not figure out why the null check is applied to actualValue
, as marked below:
ANSWER
Answered 2022-Mar-13 at 20:56The expensive()
implementation is just a demo. The idea is to allow the computation to return null and have it cached by the getter. To differentiate from the uninitialized state, it caches the AtomicReference
itself as an indication that the computation was done and returned null. It's a hacky approach, but it gets the job done.

I'm looking for a formula to check if a point on a dashed line of any length either falls onto a dash or gap.
My approach is to use the following formula
...ANSWER
Answered 2022-Mar-04 at 12:51This is an arithmetic problem, not a problem with continuous numbers. As much as possible, you should avoid floating-points and functions like Math.sin or floating-point division, which will unavoidably result in approximation errors.
Instead, modulo is a simple arithmetic answer to your problem.
QUESTION
I just seem to be stuck with the IF’s and Importhtml/Xms etc. My goal: I want a spreadsheet, where I put info like, EAN (GTIN-13), ASIN (Amazon Unique Article code). Now I want sheets to go to ebay.de & Amazon.de, take the price cheapest price from both sides - decides which price is cheaper. And subtracts 5% - this than is my finals price.
When the Article is neu or new others (Neu, Neu: Sonstige (siehe Artikelbeschreibung))
Eg. Cheapest prices: eBay 40€ - Amazon 39€ // 39€<40€= 39€-5% = 37,05€ -> if the Article does not exist on one or the other, than it will only take the number, from the existing one -5%
The system however preferably, also should see, if shipping is included and add it to the price.
Eg. Cheapest prices: eBay 40€ +5€ shipping = 45€ - Amazon 50€ // 45€<50€= 45€-5% = 42,75€
Price level: 0-100€ = -5% /// 100-1000€ = -10% //// 1000€ and more -15€
When the article is used, broken etc. (Gebraucht, Als Ersatzteil / defekt, Vom Verkäufer generalüberholt)
It only takes from ebay with the Used URL + Filter.

QUESTION
A friend gave me some code that creates a matrix that rotates from one vector to another vector. Very useful for pointing things at one another.
An issue that's come up is, often the matrix will do odd flips in its rotating. I.E. I'll end up with a result that's rotated correctly-- but is upside down in Z, or something like that.
Is there a way to add an up-vector to this code, to force the matrix to avoid rotating around the axis of the up-direction if possible?
Here's the code:

QUESTION
I am making a Javascript program and on of the functions is to convert altitude/azimuth to right-ascension/declination given a time and latitude. My code can find the declination fairly accurately, I checked with Stellarium. I have been using this site to help me with the math.
My program gives me the wrong value for horizontal ascension which I plan on using to find right ascension (I already have a function to find local sidereal time which works). Here is my code for the equation
var ha = asin(-sin(az)*cos(alt) / cos(dec)) * (180 / Math.PI);
this code is in Javascript but I defined custom sin/cos/asin functions that take degrees as input and return radians because that is the form my data is in.
The site I use also says that this equation should give the same result
var ha = acos((sin(alt) - sin(lat)*sin(dec)) / (cos(lat) * cos(dec))) * (180 / Math.PI);
but, the two equations give different results and neither are correct according to stellarium. I have checked that all the variables I am putting in are correct and I am almost certain I entered the equation correct. Here is the full code on github. I need help figuring out how to fix this problem.
--Note this can be run with node js with no libraries
The result I get is { ra: [ 23, 57, 37.9 ], dec: [ -5, 24, 38.88 ] }
It should be getting { ra: [ 5, 36, 22.6 ], dec: [ -5, 24, 38.88 ] it does not have to be exact, I only really care about the first number of ra (right ascension). It is also formatted in HMS format. The datetime is hardcoded to Febuary 1st 2022 12:00:00 so that is what you should set stellarium to if you are testing this out.
Here is the relevant code
ANSWER
Answered 2022-Feb-04 at 02:02Give the following a try. Notable changes include:
Specified 'GMT+0000' when establishing J2000.0 date, in addition to the date being passed in to
altazToradec()
. Otherwise, new Date() returns local time.Sourced calculation of 'DEC' and 'HA' from MathWorks.com (look under the "Functions" tab).
NOTE: 'HA' and 'RA' are in degrees, not hours. To convert to hours, multiply by (24 hrs / 360 deg), or simply divide by (15 deg / hr).
