Half note Half note In music, a half note (American) or minim (British) is a note played for half the duration of a whole note (or semibreve) and twice the duration of a quarter note (or crotchet). It was given its Latin name ("minima", meaning "least or smallest") because it was the shortest of the five note values used in early medieval music notation . In time signatures with 4 as the bottom number, such as or , the half note is two beats long. However, when 2 is the bottom number (including "alla breve", ), the half note is one beat
Time value of money at future time "n": Summing over all payments from time 1 to time n, then reversing t Note that this is a geometric series, with the initial value being "a" = "C", the multiplicative factor being 1 + "i", with "n" terms. Applying the formula for geometric series, we get The present value of the annuity (PVA) is obtained by simply dividing by formula_19: Another simple and intuitive way to derive the future value of an annuity is to consider an endowment, whose interest is paid as the annuity, and whose principal remains constant. The principal of this hypothetical endowment
