I am a computer guy, I am making some simulations and try to figure out something.
But there is some thing mathematical which I am not able to figure out.
This is my whole area of graph(simulation) given in picture. I have to find the distance between two points like red dots in given picture.
Distance between two points can be found with Euclidean Distance but that is for this below given type of graph. Where Y decrease when go below the 0,0. But in my case Y increase while going below.
Euclidean Distance will be suitable for my scenario or not ?
If there is any other formula can any one mention it.
Yes. It will still work just fine.
Why? Because the formula is, roughly,
EuclideanDistance = Math.sqrt( (x2 - x1) * (x2 - x1) + (y2 - y1)(y2 - y1) );If you replace both y1 and y2 by -y1 and -y2, then both factors in the second product are negated, and the product remains the same, because $-1 \times -1 = 1$.
