Is there a formula within Quickbase that would calculate the miles from one point to another if the latitude and longitude were supplied for two locations?

>I suppose that I could load up a table for the values of SIN and COS for each degree or radian but that is too much work for my needs.

You could build a relationship between the table that contained the angle field and the sine and cosine tables.

On the other hand just replace the formula language with JavaScript and it will solve all these problems. Then you could freely calculate FFT, eigenvalues, splines, linear/quadratic programming problems etc:
