\u00davod do funkce pro v\u00fdpo\u010det Besselovy funkce druh\u00e9ho druhu<\/h2>\n

Besselovy funkce jsou d\u016fle\u017eit\u00fdm matematick\u00fdm n\u00e1strojem pou\u017e\u00edvan\u00fdm v r\u016fzn\u00fdch oblastech fyziky a in\u017een\u00fdrstv\u00ed, nap\u0159\u00edklad p\u0159i \u0159e\u0161en\u00ed probl\u00e9m\u016f spojen\u00fdch s kmit\u00e1n\u00edm a vln\u011bn\u00edm. Funkce, kterou se budeme zab\u00fdvat, umo\u017e\u0148uje v\u00fdpo\u010det Besselovy funkce druh\u00e9ho druhu, ozna\u010dovan\u00e9 tak\u00e9 jako Weberovy funkce, pro zadan\u00fd \u0159\u00e1d a \u010d\u00edseln\u00fd argument. <\/p>\n

Syntaxe a pou\u017eit\u00ed funkce<\/h2>\n

Syntaxe funkce v Microsoft Excel i v Google Tabulk\u00e1ch je velmi podobn\u00e1. Pro jej\u00ed pou\u017eit\u00ed pot\u0159ebujete uv\u00e9st dva argumenty: \u0159\u00e1d funkce (n) a hodnotu pro v\u00fdpo\u010det (x). Syntaxe funkce vypad\u00e1 takto: <\/p>\n

BESSELY(n, x)<\/code><\/pre>\n
    \n
  • n<\/code> je \u0159\u00e1d Besselovy funkce a m\u016f\u017ee b\u00fdt jak kladn\u00e9, tak z\u00e1porn\u00e9 cel\u00e9 \u010d\u00edslo.<\/li>\n
  • x<\/code> je bod, v n\u011bm\u017e chceme funkci vyhodnotit. X by m\u011bl b\u00fdt kladn\u00e9 re\u00e1ln\u00e9 \u010d\u00edslo.<\/li>\n<\/ul>\n
    Ob\u011b platformy, MS Excel i Google Tabulky, vy\u017eaduj\u00ed, aby argument x<\/code> nebyl z\u00e1porn\u00fd, proto\u017ee v takov\u00fdch p\u0159\u00edpadech funkce vr\u00e1t\u00ed chybovou hodnotu.<\/p>\n
    Praktick\u00e9 p\u0159\u00edklady vyu\u017eit\u00ed<\/h2>\n
    P\u0159\u00edklad 1: V\u00fdpo\u010det specifick\u00fdch hodnot Besselovy funkce<\/h2>\n
     P\u0159edpokl\u00e1dejme, \u017ee pot\u0159ebujeme ur\u010dit hodnotu Besselovy funkce druh\u00e9ho druhu pro n=2 a x=3.5. V\u00fdpo\u010det provedeme n\u00e1sleduj\u00edc\u00edm zp\u016fsobem: <\/p>\n
    =BESSELY(2, 3.5)<\/code><\/pre>\n
     Po zad\u00e1n\u00ed tohoto vzorce do bu\u0148ky v aplikaci MS Excel \u010di Google Tabulky dostaneme konkr\u00e9tn\u00ed \u010d\u00edselnou hodnotu, kter\u00e1 reprezentuje v\u00fdsledek Besselovy funkce druh\u00e9ho druhu pro zadan\u00e9 n a x. <\/p>\n

     Pokud bychom cht\u011bli vizualizovat, jak se m\u011bn\u00ed hodnoty Besselovy funkce druh\u00e9ho druhu pro dan\u00fd \u0159\u00e1d n a r\u016fzn\u00e9 hodnoty x, m\u016f\u017eeme vytvo\u0159it \u0159adu v\u00fdpo\u010dt\u016f s r\u016fzn\u00fdmi hodnotami x a n\u00e1sledn\u011b v\u00fdsledky zobrazit v grafu. Nap\u0159\u00edklad pro n=0 a hodnoty x od 1 do 10: <\/p>\n
