I have been using the vincenty function to calculate 
distances between latitudes and longitudes.  I would now like to find 
points that are X miles from a given coordinate.  

Is anyone aware of a function that would calculate a latitude  of a new point if all other inputs are know?

For example :  

vincenty 41.75499 -124.194   ? -124.194, hav(5)    

So I  want to know the latitude of the point 5 miles away on the same longitude?  

I looked at the code in the vincenty ado file and it is beyond my mathematical ability to calculate this number myself.

Thank you.
