Recurrence formula

Japanese: 漸化式 - ぜんかしき(英語表記)recurrence formula
Recurrence formula
When there is a sequence of numbers or a sequence of functions S i ( i = 1, 2, 3, ..., n , ...), this refers to the formula that expresses S n +1 using some of the S i ( in ). For example, in an arithmetic sequence with a common difference of a , S n +1 = S n + a , and in a geometric sequence with a common ratio of r , S n +1 = rS n . In addition, integrals
So

I n ={- sin n -1 x・cos x +( n -1) I n -2 }/ n

This is also a kind of differential equation.
