Zochepetsera nusu popanda Chiwerengero

Dziko la sayansi mkulu predisposes kuonetsetsa kuti anthu ntchito zochepa. Pachifukwa ichi, zinatchuka yaikulu ntchito chakudya, ngakhale zoonekeratu zoipa chakudya thupi. kupezeka Intaneti ndondomeko kuphunzira mmene kale. Tsopano, pothetsa vuto zovuta, kupita wotchuka injini kufufuza ndi kulowa mbali ya ntchito mubokosi losakira. Chifukwa cha opangidwa yopuma dziko lonse amayamba pang'onopang'ono amanyoza.

Anthu ambiri masiku ano sadzatha kufotokoza ana awo zochepetsera nusu, makamaka ngati si maziko ntchito ndi manambala. Osati kutchula mitunduyi trigonometric ndi zochita. Ife tilibe kukhala kwa mphindi zisanu kukumbukira zimene zinachitika pa sukulu. Ndipo ngakhale chakuti tikhoza lucidly kufotokoza zimene adzatha kumbukirani.

tuzigawo twa zosayenera ndipo kusinthika awo

nusu A, ndi numerator umene phindu lake ndi wamkulu kuposa chimene chachititsa amatchedwa osasamba. Kuunikila ndi chigawo lonse, kumtunda kwa kachigawo kuti kugawidwa pansi. The quotient wa wolembedwa mosiyana ndi yotsala anaikidwa numerator lapansi. Chimene chachititsa Pankhaniyi kukhala sichinasinthe.

Tuzigawo twa ndi zosintha

Ngati mmene muli numerator ndi chimene chachititsa wa kachigawo muli kalata, kuchepetsa ake ali motere:

1. Ngati makalata osiyana, inu mukhoza kupita ku kuchepetsa chiwerengero:

2a / 4c = ndi / 2c

2. Ngati zosintha yemweyo:

3as / 7skh = 3a / 7x

3. choncho kumene pali madigiri, ndiye yemweyo maziko kachigawo amapezeka ndi kuchepetsa wochotsera wa kunadetsa wamng'ono:

^{3 7/3 12 = 3 0} /3 12-7 = 1/3 5

4. Zimenezi zimagwiridwa pa nthawi imene pali digiri ya variable ndi:

ndipo ¹² kwa ³ / wa = ⁵ mpaka ¹⁰ ndipo ^12-10 / K = ^3/5 ndi ² / K ²

Ngati kumene zapansi ndi osiyana, sikutheka kuchepetsa nusu.

Tuzigawo twa munali mawu

Zochepetsera nusu, ndi numerator amene ndi ndalama kapena kusiyana? Zikatero m'pofunika kutsatira mfundo Acronym chulutsa kapena kufalitsa mawu factorization. M'pofunikanso kukumbukira kuti numerator ndi kuchuluka kuti akhoza kudula yekha pa nkhani ya mwangozi wathunthu chimene chachititsa kuti:

(A + h) / (a + h) ² = 1 / (a + h) ndi (a + h) / wa = ndi / munthu + K / K = ndi / 1 +

Mwachitsanzo, mmene tingachepetsere nusu ya mawonekedwe:

(4k + ² 4kr + tsa ²⁾ / (2k + p)

Kuti akwanitse kuchepetsa ntchito ndi lalikulu osiyanitsidwa Uwerenge chilinganizo mu numerator ndi ife kupeza:

4kr 4k + ² + tsa ² = (2k + p) ²

Tsopano kuti numerator ndi chimene chachititsa ndinu yemweyo, sitingachitire mwina, zochepetsera nusu:

(2k + r Mukhoza) ² / (2k + p) = (2k + p) / 2k + 1 = tsa

Pofuna mosavuta kuchepetsa nusu, muyenera kukhala bwino ndi ntchito mitunduyi waluso wa chulutsa abridged. Pakuti ambiri, zikuoneka kuti vuto lalikulu, koma nthawi zambiri iwo ntchito iwo ali mwangwiro kusungidwa. Akufotokozera ubongo wa munthu, zingamuthandize kuti aone yankho la mavuto zosamvetsetseka.

njira wangwiro zochepetsera nusu, ndi kuchuluka kwake. Zimenezi zimathandiza kupereka mpata kwa gawo kulenga, pamodzi ndi aluntha lapansi. Ngati tinaganiza kukakamiza ana awo zitsanzo izi nokha, kotero tingawathandizire kuti azolowere mwamsanga kusintha ndipo motsatana mwadzidzidzi moyo.
