Find the shortest distance -Earth Geometry

[ntalashateddy]

Shortest distance under earth geometry is the distance along the great circle(meridian) via the north or south pole. With this definition in mind, that makes me to question the accuracy or authenticity of your calculations.

Where did u get that first formula sir

Wow clear ex
planation thank you ❣️ Sir

I have seen a situation where distance is considered along the great circle. Why are we not having an element of π and 360 when we know that the earth is spherical. Am lost. I am getting a different answer when I consider the path along the great circle. Please help.

What if the latitudes of the points is different? For example 20 degrees south and 60 degrees north?

🙋I have a question sir. What about in the case where (π) is given and (R) as well and the question is to find the shortest distance along either latitude or longitude. Is (π) supposed to be included in the formula or just using the same procedure you've shown here?

Thank you so much sir for your work, I loved method 2 as it is easy to figure out by using the knoweledge from trig.
