Scientific calculator plus 991

Isayensi wokubala 300 plus, 991 umshini wokubala wezitshudeni nomfundi wobunjiniyela. I-Calculator 991 plus inikezela ngemisebenzi enamandla ekubaleni kwangempela 991 300. Kwenza ukubala okuthuthukile 991 kube umshini wokubala owusizo kakhulu weyunivesithi nesikole.

Uhlelo lokusebenza lufaka okokubala ngaphakathi:
- Isilinganiso sokubala esingu-300 kanye
- Isibali sokuthuthuka esingu-115 plus
- Isayensi yokubala 991
- Isayensi yokubala 991 plus
- Isibali sokubala i-84 plus

Ake sibheke ezinye izici ezikhethekile:

◉ Isisekelo sokubala esingu-300 kanye no-115 plus: isekela kusuka kumathematics ayisisekelo kuya kwimisebenzi yezibalo esezingeni eliphakeme: amaphesenti, amandla, izimpande, ama-trigonometric, ama-logarithms wokubala. Isibalo seengxenye 991 sisekela ukuguqula ingxenyenamba ibe yedijithali, ingxenyeni exubile nokuxazulula izinkinga zezingxenyana.

◉ I-Calculator esezingeni eliphakeme eyi-115 plus: ihlanganisa i-hyper wokubala ne-calc elula yesayensi. Le wokubala iyinhlangano esebenza ngokweqile esezingeni eliphakeme yokubala 991 enazo zonke izici kuhlelo lokusebenza olulodwa. Njenge-algebra emugqa, isibalo, izinombolo eziyinkimbinkimbi, umphumela wokukhombisa ukuxhumanisa okungunxande kanye ne-polar, matrix ne-vector.

Calcul Isayensi yokubala 991 plus: ifaka i-smart equation solver. I-equation solver ingaxazulula ama-quadratic, zibalo zama-cubic, amasistimu wezibalo. I-caluculator ixazulula noma iyiphi i-polynomial. Isibalo sokubala se-Smart 991 sinesibalo sokuqagela equkethe izibalo zesayensi ezinjenge-derivative, ebalulekile, ukubalwa kwezimpande zesikwele, ukubalwa kwe-factorial, ukubalwa kwe-pi, i-equation solver.

Calcul Isayensi yokubala 991: isekela ukubalwa ngenani lamanani wamadijithi, izinto eziyinhloko, izinombolo ezingahleliwe, inhlanganisela, izimvume, i-GCD ne-LCM. Le wokubala 991ex kuyinto Simulator wangempela kwezobunjiniyela. Okokubala kwesayensi kunezici ezingama-500 es, 500 ms, 300 es plus, 991 es plus. Isakhiwo sekhibhodi ye-Calculator sifana ne-wokubala engu-300 es plus, 991 ex ne-es plus.

◉ Isilinganiso sokubala esingu-84 plus sisekela umsebenzi wegrafu, polar, parametric nomsebenzi ocacile. Isibalo sokubala i-84 singadonsela phezulu, ukulandela umkhondo, ukukhipha, izimpande, amaminithi ne-max. Ilinganisa i-graphic caluculator 83 ne-t1 84, 84 plus.

◉ I-Calculator ehlanganisiwe ye-991 plus inikezela nge-wokubala enamandla ukubala ukuhlanganisa, ukukhipha, ukwahlukanisa nokuhlanganiswa.

◉ Le wokubala 991 yesayensi ifaka i-CAS (i-computer algebra system), engakwazi ukubala okungokomfanekiso.

◉ Ezinye izici: ifomula zezibalo, ifomula yefizikhi, ukuguqulwa kwento, itimu, ifonti nokuhlelwa.
