I have some questions regarding a puzzle.
This is a logarithmic spiral, and i know that from "Startpunkt" to "A" the direct distance is 86,23. From "Startpunkt" to "B" the direct distance is 75,41.
If i start at "Startpunkt" and measure the spiral where will the point be when the distance is 3000 ?
I have found the definition r = ae^(b*theta), but i don't know how to use it. How do i find the two constants a and b ?
And how do i find the length ?
