I have an equation that calculates the distance between two coordinates on Earth. The problem is, I need to rewrite this equation to solve for a different variable.
D=Distance in feet
A=Some place's longitude
B=Some place's latitude
D=5280*(SQRT( (69.1*(B-Y))^2 + (69.1*(A-X)*COS(Y/57.3)) ))
How can I rearrange this equation to solve for A not D?
