I bit dissapointed, because my main interest was to learn about haversine formula. The whole video is cool, but the amount of attention paid to the formula is a wasted potential. If you have a video about it specifically, could be cool to add the link in the description!

We’ll fun fact, the shape of the earth looks like an ellipsoid potato and it’s not a perfect sphere. So we instead use a very complicated formula that works out real distances based on Einsteins theory of relativity. It takes in to account the gravitational force which can be used to model the shape of the earth.😅

ok, with the haversine formula at the end, how are you getting 2827.7? because I've put it in my calculator multiple times with different bracket arrangements to try and get that, but I just keep getting 2842? So I don't know if I'm doing it wrong or if you have the wrong answer? And If I am doing it wrong WHAT am I doing wrong? If I understand correctly, arccos is cos-1 on the calculator? So in my calculator I'm putting: 3440.1*acos((sin(0.488)*sin(-0.244))+cos(0.488)*cos(-0.244)*cos(-0.122-0.261)) and the answer comes up as 2842.0105435058

To get .1 NM precision will require 5 decimal places--not just 3. .28° is not 488 radian. It is nearer .489 radian. In this task it is to be written as .48870 radian. -14° = about -.24435 radian. The change in longitude is properly found by subtracting the exact longitudes, then converting to radians. -21° is about -.36652 radian. (Using -.383 radian would cause 21 NM of error.) [For exactitude, when calculating you could key in: (28° × pi ÷ 180°), (-14° × pi ÷ 180°), and (-21° × pi ÷ 180°). Your calculator knows pi to more than 5 places]. The distance from formula is about 2801.9 NM.

It's 18,75 not 18,45. You can do this because there are 60 minutes in a degree. If you subtract the numbers the way they are, it can be hard to remember what you need to subtract while doing the math. So instead we represent the number in a different way that's easier to understand.

Great video but I am currently faced with another way of calculating the shortest distance that I can't find any info on. Have you covered it in the past? It goes as follows. Given A=60°N 10°E B=50°N 170° W. The shortest route doesn' t follow the 60 parallel but a great circle 10°E 170°W. So from the 60°parallel to the pole is 30° (How do I get this difference?) From the pole to the 170°W meridian is 40° (again how do I get this?) So 30 + 40 = 70 × 60 = 4200 minutes = 4200nm. What is this method called and do you cover it? I don't know how to get the difference from the pole using basic measurement tools allowed on exams. Update: I just realized the pole is 90° not 0, silly me... that solves the degree difference.

You can make your own system, though. I would stick to the decimal numbers included in the GPS info with +/- for N/S and E/W. Google maps use both. Minutes and seconds are just fractions of a degree. A latitude becomes +/-58.97754453 as an example. Quite easy to convert with 0.97754453*60 where the whole number is the result for minutes and the remainder is an extra 60 times (60*60).

You can find the distance between the two points through de Haversine formula (let's call this distance "d"), and then, given that a great circle measures 40,000 km, the angle between the two points will be: angle = (d/40,000) * 360º
