Tam sim no, cia li nias nkag mus ntsuas qhov factorial !

Hais txog qhov no, qhov twg yog lub khawm factorial ntawm TI 84 Plus?

Yog tias koj tseem tsis tau ua tiav, nias [2nd][MODE] mus rau lub vijtsam hauv tsev. Ua raws li cov kauj ruam no los ntaus a factorial hauv koj lub laij lej: Sau tus lej koj xav coj tus lej factorial ntawm. thiab nias [4] xaiv lub factorial cim (nws zoo li lub ntsiab lus exclamation.)

Ib tug kuj yuav nug, qhov twg yog qhov sib npaug ntawm kos npe rau TI 84 Plus CE? Nias koj lub laij lej 2nd khawm, nyob rau sab saum toj sab laug ces kaum, ua raws li MATH/TEST khawm ntawm sab laug. Qhov no ua rau TEST cov ntawv qhia zaub mov ntawm kev sib raug zoo.

Kuj nug, qhov twg yog lub pob permutation ntawm TI 84?

Cov mis rau kev sib xyaw ua ke yog: nCr = (n!)/(r!(n-r)!).mus rau Math PROB menu lossis nias [ALPHA][WINDOW] nkag mus rau cov ntawv qhia luv luv. mus saib tau cov ntawv qhia zaub mov uas koj yuav nrhiav tau kev hloov pauv thiab cov lus txib sib txuas. Siv cov TSI - 84 Ntxiv rau, koj yuav tsum sau n, ntxig cov lus txib, thiab tom qab ntawd sau r.
