Music of the Trecento system of division of the breve into 2, 3, 4, 6,8, 9, or 12 semibreves (later minims) with dots (singular "punctus divisionis") indicating breaks at the end of a breve (however, Marchetto never used a term 'punctus divisionis'). Although more Trecento music is written in the international system of notation descended from Franco of Cologne and Philippe de Vitry than in the Marchettian system (and there exist a few, mostly instrumental, works not of Italian origin that use this system), nonetheless, Marchetto's contribution to rhythmic notation is so connected with the Italian Trecento that it is often referred to as
Time value of money growth and true perpetual cash flow generation. Despite these qualifications, the general approach may be used in valuations of real estate, equities, and other assets. This is the well known Gordon Growth model used for stock valuation. The future value (after "n" periods) of an annuity (FVA) formula has four variables, each of which can be solved for by numerical methods: To get the FV of an annuity due, multiply the above equation by (1 + i). The future value (after "n" periods) of a growing annuity (FVA) formula has five variables, each of which can be solved for by
