Explicit Formula for the n-th Derivative of a Quotient

Roudy El Haddad

Leibniz's rule for the $n$ -th derivative of a product is a very well known and extremely useful formula. In this article, we introduce an analogous explicit formula for the $n$ -th…

Repeated Sums and Binomial Coefficients

Roudy El Haddad

Binomial coefficients have been used for centuries in a variety of fields and have accumulated numerous definitions. In this paper, we introduce a new way of defining binomial coef…

Repeated Integration and Explicit Formula for the $n$ -th Integral of $x^{m} (ln x)^{m^{'}}$

Roudy El Haddad

Repeated integration is a major topic of integral calculus. In this article, we study repeated integration. In particular, we study repeated integrals and recurrent integrals. For…

Multiple Sums and Partition Identities

Roudy El Haddad

Sums of the form $\sum_{q \leq N_{1} < \dots < N_{m} \leq n} a_{(m); N_{m}} \dots a_{(2); N_{2}} a_{(1); N_{1}}$ date back to the sixteen century when Viète illustrated that the relation linki…

Recurrent Sums and Partition Identities

Roudy El Haddad

Sums of the form $\sum_{N_{m} = q}^{n} \dots \sum_{N_{1} = q}^{N_{2}} a_{(m); N_{m}} \dots a_{(1); N_{1}}$ where the $a_{(k); N_{k}}$ 's are same or distinct sequences appear quite often in mathema…
