14 Mart, her y\u0131l D\u00fcnya Pi G\u00fcn\u00fc olarak kutlan\u0131r. Pi say\u0131s\u0131n\u0131n ilk \u00fc\u00e7 basama\u011f\u0131 3.14 oldu\u011fundan, 3. ay\u0131n 14. g\u00fcn\u00fcnde kutlanmaktad\u0131r. Bu tarih, ABD’de kullan\u0131lan tarih format\u0131 olan 3\/14 olarak belirtilir. Di\u011fer \u00fclkelerde de ayn\u0131 “\u00f6zel g\u00fcn” ya\u015fan\u0131r; ancak tarih format\u0131n\u0131n farkl\u0131l\u0131\u011f\u0131ndan dolay\u0131 14\/3 \u015feklinde g\u00f6sterilir ve 3.14 olamaz. Baz\u0131 b\u00f6lgelerde ise 22 Temmuz (22\/7) g\u00fcn\u00fc, pi say\u0131s\u0131n\u0131n kesirli g\u00f6sterimini temsil etti\u011fi i\u00e7in Pi G\u00fcn\u00fc olarak kutlanmaktad\u0131r.<\/p>\n
Pi, bir irrasyonel say\u0131 olmas\u0131 nedeniyle sonsuz basamaklara sahiptir. Bu nedenle pi say\u0131s\u0131n\u0131n tamam\u0131n\u0131 yazmak m\u00fcmk\u00fcn de\u011fildir. Ancak kesir kullanarak yakla\u015f\u0131k bir de\u011fer elde edilebilir. \u00d6rne\u011fin, pi say\u0131s\u0131n\u0131 3, 3.1 veya 3.14 gibi k\u0131sa haliyle kullanmak m\u00fcmk\u00fcnd\u00fcr. Ancak baz\u0131 b\u00f6lgelerde bu basamaklar\u0131n ka\u00e7 tanesine ihtiya\u00e7 duyuldu\u011fu tart\u0131\u015f\u0131labilir.<\/p>\n
Pi sembol\u00fcyle g\u00f6sterilen say\u0131, bir \u00e7emberin \u00e7evresinin \u00e7ap\u0131na oran\u0131n\u0131 ifade eder. Yani bir \u00e7emberin etraf\u0131n\u0131n \u00e7ap\u0131na b\u00f6l\u00fcnmesi sonucu pi say\u0131s\u0131 elde edilir. \u00c7emberin \u00e7ap\u0131 ne olursa olsun, bu oran her \u00e7ember i\u00e7in ayn\u0131d\u0131r. Pi say\u0131s\u0131 yaln\u0131zca \u00e7emberlerde de\u011fil, rastgele y\u00fcr\u00fcy\u00fc\u015flerde, sarka\u00e7larda ve rastgele say\u0131 dizilerinde de kar\u015f\u0131m\u0131za \u00e7\u0131kar.<\/p>\n
Pi’nin tamam\u0131n\u0131 kullanmak yerine sadece belirli bir k\u0131sm\u0131n\u0131 kullanmak da m\u00fcmk\u00fcnd\u00fcr. \u00d6rne\u011fin, 3.14 gibi k\u0131salt\u0131lm\u0131\u015f bir form\u00fcl kullanmak yayg\u0131nd\u0131r. Ancak hangi basamaklar\u0131n kullan\u0131laca\u011f\u0131 ve ne kadar\u0131n\u0131n yeterli olaca\u011f\u0131 tart\u0131\u015fma konusudur. Trigonometrik fonksiyonlar\u0131 hesaplarken de benzer \u015fekilde belirli bir k\u0131sm\u0131 kullanmak yeterli olabilir.<\/p>\n
NASA, uzaydaki mesafeler gibi hesaplamalarda pi say\u0131s\u0131n\u0131n ilk 15 basama\u011f\u0131n\u0131 kullanmaktad\u0131r. Bu, \u00f6nemli m\u00fchendislik konular\u0131nda yeterli bir hassasiyet sa\u011flamaktad\u0131r. Pi say\u0131s\u0131n\u0131 15 basama\u011fa kadar kullanmak, pratik t\u00fcm ama\u00e7lar i\u00e7in genellikle yeterli olmaktad\u0131r. NASA’n\u0131n bu tercihi, uzay m\u00fchendisli\u011fi gibi konularda g\u00fcvenilir hesaplamalar yapabilmek i\u00e7in \u00f6nemlidir.<\/p>\n","protected":false},"excerpt":{"rendered":"
