My Dear Friend,
Thank you for your attempt of understanding the math.
The idea behind your attempt to disprove the math of great circles, will not resolve the problem with the simulator, or the challenges you have in understanding the proof.
Even if the numbers are incorrect, which anyone can make a mistake… will not change the fact that you need to put an effort into disproving my point.
Otherwise enjoy putting your time into more productive challenges, that way your brain will get smarter.
Changing numbers will not change the fact that I am right.
And sorry for my productive thinking, I seem to enjoy smart arguments… rather then shallow ideas.
