Tus nqi ntawm ib qho nyuaj Tus lej. Cov tag nrho tus nqi ntawm ib tug complex tus lej, a + bi (tseem hu ua modulus) yog txhais raws li qhov kev ncua deb ntawm keeb kwm (0, 0) thiab point (a, b) hauv complex dav hlau.
Ntawm no, tus nqi ntawm Z yog dab tsi?
Tus lej complex z feem ntau yog sawv cev los ntawm ib khub xaj (a, b) hauv lub dav hlau complex. Yog li ntawd, lub tus nqi kiag (los yog modulus) ntawm z txhais tau tias yog tus lej tiag Square hauv paus ntawm√a2 + b2, uas sib raug rau z li deb ntawm lub hauv paus chiv keeb ntawm lub complex dav hlau.
Ib tug kuj nug, koj puas tuaj yeem muab tus nqi tiag? Thawj kauj ruam yog los tswj cov tus nqi kiag ntawm x rau hauv daim ntawv sqrt(x^2) thiab tom qab ntawd siv txoj cai saw rau kev sib txawv. Nco ntsoov tias derivative ntawm tus nqi kiag ntawm x tsis txawv ntawm x = 0.
tus nqi ntawm 2 2i yog dab tsi?
Teb thiab piav qhia: Lub tus nqi kiag ntawm tus lej complex, 2 ib i , yog 2 . Peb tuaj yeem muab tus lej complex, 2 ib i , nyob rau hauv daim ntawv a + bi los ntawm cia a = 0. Qhov ntawd yog, 2 ib i = 0 + 2 ib i . Yog li, a = 0 thiab b = 2.
Dab tsi yog qhov modulus ntawm tus lej complex?
Modulus ntawm Complex Number . Kev txhais ntawm Modulus ntawm Complex Number : Cia z = x + iy qhov twg x thiab y yog tiag thiab i = √-1. Ces qhov tsis zoo square cag ntawm (x2+ y 2) yog hu ua modulus los yog tus nqi ntawm z (los yog x + iy).

Yuav ua li cas koj nrhiav tau tus nqi ntawm ib tug particle?
Nyob rau hauv physics, ib tug nqi particle yog ib tug particle nrog ib tug hluav taws xob nqi. Tej zaum nws yuav yog ib qho ion, xws li cov molecule los yog atom nrog ib qho nyiaj seem lossis tsis txaus ntawm cov electrons txheeb ze rau protons. Nws kuj tuaj yeem yog electron lossis proton, lossis lwm yam khoom siv hauv tsev, uas txhua tus ntseeg tias muaj tib yam nqi (tshwj tsis yog cov tshuaj tiv thaiv)
Yuav ua li cas koj thiaj nrhiav tau tus nqi ntawm tus qauv txhais tau tias?
Qhov xav tau tus nqi ntawm tus qauv txhais tau tias yog cov pej xeem txhais tau tias, thiab SE ntawm tus qauv txhais tau tias yog SD ntawm cov pej xeem, muab faib los ntawm lub hauv paus square ntawm tus qauv loj
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Yuav ua li cas koj nrhiav tau tus sau ntawm ib tug algebraic muaj nuj nqi?
Lub luag haujlwm ntawm ib qho kev ua haujlwm yog cov txheej txheem ntawm tag nrho cov khoom siv tau rau kev ua haujlwm. Piv txwv li, lub npe ntawm f (x) = x² yog tag nrho cov lej tiag, thiab lub npe ntawm g(x) = 1 / x yog txhua tus lej tiag tiag tshwj tsis yog x = 0
