Delphi için yazılmış bir çok matematiksel fonksiyonları barındıran bir site.
integral yöntemleri ile ilgili daha önce arkadaşlara kullanmalarını söylediğim fonksiyonların neredeyse hepsiyle ilgili örnek verilmiş burada.
CRC ile ilgili örnekler var.
Varda var... öğrencilerin işine epey yarıyacak bir site
