i am working on a project and i need t know how to randomly set a map marker in a 5x5 mile circle around the user.
Do you mean randomly on a circle with a radius of 5 miles? (always exactly 5 miles from the user) or within the circle with a radius of 5 miles from the user? These are two different problems.
Would you really like to draw a circle of radius 5 miles from the user on the map. This is easier than randomly plotting Markers on the circle circumference.
You need to know that .0723049 degrees is approximately 5 miles. Actually this is not exact. Although the distance between latitude degrees are always the same; the distance between longitude degrees varies as one moves away from the equator.
