Hi there,
r is the radius, r^2 = x^2 + y^2, or r = sqrt(x^2+y^2). There are two
ways to work with the dates. Either in Excel, where you can enter
them and calculate the difference (or, more accurately, the business
days between them) and then you can use MSFL. If you plot something
like the Cum(1) function, it can serve as the X axis, going from 0 to
where ever. You can do this in MSFL, and we have had such examples
here with lines and ellipses some time ago. You can try it, or note
the value of the Cum(1) function at the two points. This should give
you x0 and x1. Then note the value of the trendline at these points
and you have y0 and y1. In excel, calculate
r = sqrt(x0*x0 + y0*y0)
and
angle = asin( (y1-y0) / r )
This gives the angle in radians (I think), so to get to degrees, use
something like
degrees = angle / ( 2 * PI ) * 360
