Bu makalenin
temel amacı normalize edilmiş hata fonksiyonunun kısmi toplamlarına oranının
reel kısımları için bazı alt sınırlar belirlemektir. Ek olarak, normalize
edilmiş hata fonksiyonu ve türevinin mutlak değerleri için bazı üst sınırlar da
verilmiştir.

On Partial Sums of Normalized Error Function

Öz

The main purpose of this paper is to determine some
lower bounds for real parts of the quotient of normalized error function and
its partial sum. In addition, the some upper bounds for absolute values of
normalized error function and its derivative are also given.
