Consider a continous annuity whose density is annual variable in arithmetic progression with first payment 101 euro and ratio 23 euro, for 3-years.

Consider a continous annuity whose density is annual variable in arithmetic progression with first payment 101 euro and ratio 23 euro, for 3-years.

Compute its present value knowing that the semestral intensity of interest is 1% for the first year and 2 days, null for the following 28 days and then it is equal to S(t) = (1/(1+0.005t)) [instantaneous convention]
