Amazing explanation ! Thank you so much sir ! 🙏. Every detail was mentioned methodically, stage by stage you have reasoned out every single feature asked in the question , made it so simple and easy to follow , although it was quite a lengthy numerical involving the COSINE rule, followed by the NAPIERS formula , expressing the vertex and intermediate point ? honestly ! I do consider this a very interesting and comfortable solution to the G.C sailing numerical explained by you with great effort n expertise to help many aspiring officers in the maritime industry ? Thank you very much indeed sir ! God bless you and your family immensely 😇🙏

Thank you for the excellent video. This is exactly what I needed to understand this!

THANK YOU SOOOOOOOOOOO MUCH SIR. I UNDERSTOOD WELL. GOD BLESS U SIR

You work is tremendously great, how ever Im watching over and over again but i could not imagine how are you going to plot your solving in actual chart or map, hoping in your next video tutorial,, transfering or plotting of great circle as actual line on a nautical chart,even just on large scale would be fine sir. Many thanks,

Thank you sir for solving this problem

Many many thanks sir

Thank you sir❤

Sir,what if by cosine rule we get value more than 90 degree

excellent mathematics

can someone please explain how to divide your initial position and final position into legs?

Sir how to determine the triangle for calculating the position of vertex when its not inside the triangle i.e when the initial and the final course are in different quadrant

Nice awesome sir thank you 🙏

Sir, If dlong is 90 or more than 90 then vertex should be between A&B in samehemisphere , is it correct ?

Sir how to determine latitude of gc track cross the meridian 180 deg. Pls upload the vedio asa possible.

Sir.... Ur explaination is good, but ur voice is very low... Even in the loud speaker.. So try to speak somewhat loud...once again tq, ur awesome sir👏👏

Sir can u plz make 1 more video on this

Best One

Sir I think you have to give the name of part Name as like great circle sailing

If one of your latidude is on North and the other is on south, and your pole is at North..how will you calculate PB?

sir what happens when the initial co. and final co. are in the same quadrent ??

Where did angle p came from please explain! Is that given in question

I understood the problems and how to do it but i have confusion with direction of d'long

can u pls tell me how to name final course

Have you got any evidence that great circle ⭕️ routes are circles and not straight line distances ? As you seem to be doing a whole load of unnecessary maths here for no reason, if you just treat it as flat and forget your sphere Belief for a minute then you would have an easier job. What is the purpose of the Haversine formula, is not to only mathematically add in a belief structure ?

But final course angle is less than 90 degree

Your voice is very slow.. can't read clearly.. pls increase your laptop voice to get clear picture..
