I get some GPS coordinates from Google Maps and I need to find the distance between them using Objective C. I have implemented the formula but I get results that are way to big.
I noticed that translating 开发者_如何学Cradians to degrees and vice versa is like translating a percentage to a whole number and vice versa. For example, to get 60 percent of 345 you do the following
My problem: given x and y, I need to calculate the x and y for the required joystick deflection. This is simple when there is no joystick deadzone -- I just use the x and y with no manipulation.
Currently I have two larger vectors of 50+ strings I want to be able to compare these two Vectors and work out how similar they are. I think I need to use Cosine similarity?
Ok. So I guess thing would to be envision new york city and beijing highlighted on google earth... I\'m trying to figure out how to map points onto a 3d primitive object (a sphere), get their distanc
i have built an index in Lucene. I want without specifying a query, just to g开发者_JS百科et a score (cosine similarity or another distance?) between two documents in the index.
Does anyone know a (preferably fast) way to calculate the sine of an angle in 4.12 fixed point? (where the result is either 32768ths of a c开发者_JAVA技巧ircle or degrees)
Given a coordinate (lat, long), I am trying to calculate a square bounding box that is a given distance (e.g. 50km) away from the coordinate.So as input I have lat, long and distance and as output I w
I know this is quite easy trigonomety, however I was never introducted to vectors etc, and I\'m at a loss understanding how this works.
Assuming the upper left corner is (0,0) and I\'m given an angle of 30 degrees, a starting point of (0,300), a line length of 600, how do I calcul开发者_开发百科ate the ending point of the line so
