Hi all
I am trying to find a quick way of checking my solutions in a test for varying annuities [(IA)angle n, (DA)angle n, and geometrically increasing and geometrically decreasing annuities]. The only link I found is this http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&dlc=en&docname=bpia5219 which is error-prone and has logical flaws within the instructions. Moreover it does not cover all cases.
Help…
