The chosiyana cha ntchito ndi a ntchito zomwe zimasintha "zotsatira" za choyambirira ntchito. Kupatsidwa a ntchito, nenani f(x), kuti mupeze mosiyana cha ntchito, timayamba kusintha f(x) kukhala y. Kenako, timasintha zonse x kukhala y ndi y kukhala x. ndiyeno timathetsa y. Yankho lopezedwa la y ndilo mosiyana cha choyambirira ntchito.

Anafunsidwanso, mumapeza bwanji kusintha kwa ntchito?

Kupeza Zotsutsana ndi Ntchito

  1. Choyamba, sinthani f(x) ndi y.
  2. M'malo mwa x aliyense ndi y ndikusintha y aliyense ndi x.
  3. Konzani equation kuchokera mu Gawo 2 pa y.
  4. Sinthani y ndi f−1(x) f − 1 (x).
  5. Tsimikizirani ntchito yanu poona kuti (f∘f−1)(x)=x (f ∘ f − 1) (x) = x ndi (f−1∘f)(x)=x (f − 1 ∘ f) (x) = x zonse ndi zoona.

Mofananamo, kodi ntchito yosiyana ndi chiyani perekani chitsanzo? An ntchito yosiyana ndi a ntchito izo “zidzasintha” chirichonse chimene choyambirira ntchito amachita. Za chitsanzo, tonsefe tili ndi njira yomangira nsapato zathu, ndipo momwe timamangira nsapato zathu tingatchulidwe kuti a ntchito. Ntchito ziwiri za masamu zomwe zikuchitika mu ntchito f(x) ndi kuchulukitsa ndi kuchotsa.

Apa, kusinthika kwa ntchito kumatanthauza chiyani?

Mu masamu, an ntchito yosiyana (kapena anti-ntchito) ndi a ntchito kuti "amatembenuza" china ntchito: ngati ntchito f yogwiritsidwa ntchito pakulowetsa x imapereka zotsatira za y, kenako kugwiritsa ntchito zake ntchito yosiyana g mpaka y amapereka zotsatira x, ndi mosemphanitsa, mwachitsanzo, f(x) = y ngati ndipo kokha ngati g(y) = x.

Kodi kusiyana kwa tchimo ndi chiyani?

The mosiyana amagwiritsidwa ntchito kupeza muyeso wa ngodya pogwiritsa ntchito ma ratios kuchokera ku trigonometry yoyambira kumanja. The mosiyana ya sine imatchedwa Arcsine kapena pa calculator idzawoneka ngati asin kapena tchimo-1.
