• #### A reply onConversation: What is the calculation for longitude?

Oct 2 2012: That is what I thought but figuring out Latitude was the easy part but the algorithm for Longitude is proving a task. Not as simple as one would think...

Oct 2 2012: Quite alright if this is deemed inappropriate was just trying to get some new mental juice in the equation...

Oct 1 2012: Not homework!!!! This has been a project that I have been working on for a few months now will let someone continue the work if I knew they would not scrap the Idea... Fritzie can back me up on that one...

Oct 1 2012: If I could use both the same calculation how would I determine sign change and the fact that it is a circle...

The prime meridan Idea Is not going to work on this end because we are wanting a non specific calculation system that while be defined by the observer not pre diagnosed regulations...

Google I have no clue but I am returning Excellent Latitudes but Longitude Is all over the map If I can pin down why then I can solve it but I first have to Iron out my logic...

I JUST DON:T KNOW YET...

Oct 1 2012: The wheel has yet to be created we know what it is with quadrants or four quarters of a circle but to navigate a variety of circles without restraints or errors is the true mastery we must find.

Oct 1 2012: Actually, I would like to say sorry for not keeping track of this post but I know what is happening with longitude but I can't explain why thing are working the way they are...

Since longitude handles four hemispheres it required two sign changes one for Southeast Northwest and NORTHEAST or SOUTHWEST...

But I had latitude at a right angle from the equator to the axis of the observer latitude then from the axis the longitude spreads out to form a new diameter at the observed latitude.

Again I not sure if I have the calculations right but the process of what is happening is locked down...

The first green is latitude the the other Items stacked are Longitude

Here are the two videos that tested the equation...

I do thank everyone in the videos they do not plea for money at this point but I do need help testing the equation so If others could test it out and then tell me what is happening I will not beable to do extensive testing for a week and a half...

The circle has a left and right and can be above or below the equator... This handles the equations needed to calculate Longitude... Since Latitude is always positive because Pythagorean Theorem is required to calculate; I know I am correct in my thought process it is now Ironing out the equations needed.

Sep 30 2012: If I turn the time of day into the prime meridian then I can figure out what degree of change the observer is from that point in time...

KEEP THE STIMULATION OF ANSWERS COMING WE WILL CRACK THIS BEFORE THE END OF THE REstricted time...
• #### A reply onConversation: What is the calculation for longitude?

Sep 30 2012: Totally correct... I can get half the world right it is the other half that Is off The equations signs are mixed up I will think about this... Thank you so much...
• #### A reply onConversation: What is the calculation for longitude?

Sep 30 2012: GOOD now visualize what the equation is facing...

Latitude and longitude are the restrictions to times equation but longitude is restricted by times calculation literally....

I can calculate latitude from the equator because it is a simple distance from 0, so observer is how far from 0?

Now how do I ask the same question for longitude in math equivalant terms?

The steps of the excel are

AVERAGING
CIRCUMFERENCE
PYTHAGOREAN THEOREM (Latitudinal step of calculation...)
• #### A comment onConversation: One more time: Can I help you find a TEDTalk you remember watching?

Aug 17 2012: I have been looking for one about neural pathways of the childs brain. They show a brain scan of a 3 yr old and a 7 yr old... If you could help that would be amazing...
