Processing already comes with a function to calculate the distance between two points in 2d and 3d. /** * Compilation: javac GreatCircle. If the car with greater velocity(in this case car B) is moving ahead, there is no chance of overtaking the other car A and hence the position-time graphs will not intersect, both the lines move far from each other as shown in the graphThe formula is a^2+b^2=c^2 (a squared + b squared = c squared), so you need to use +, not -. This means that calculating the distance between first and last and then calculating distance between last and first will not be same, as in the second case, it will have a negative sign associated with it, since we are moving backwards. 2. C++. To find the distance between two points (x 1, y 1) and (x 2, y 2), all that you need to do is use the coordinates of these ordered pairs and apply the formula. The distance formula is derived from the Pythagorean theorem. 1. We can get above formula by simply applying Pythagoras theorem.

I mostly wanted to emphasize how much better the improved formula from Wikipedia is (thanks for the pointer), while being barely more computationally costly than the classical Haversine formula: it seems one should always use the improved formula, rather than Haversine. I have updated the OP with what the code should look like if you're trying to find the distance. And this formula is not very good. I was having problems with my algorithm because the results are about 10 times larger than expected. Substituting the values in the above formula. 2. Pad the shorter binary string with leading zeros to make both strings of equal length. All you have to do to get the distance between two points (q1,p1) and (q2,p2) is use the coordinates of these ordered pairs and apply the abovementioned formula.
