Trigonometric muaj nuj nqi yog qee zaum hu ua ncig ua haujlwm . Qhov no yog vim ob lub hauv paus trigonometric muaj nuj nqi - cov sib thiab cov cosine - txhais tau tias yog qhov chaw ua haujlwm ntawm qhov taw tes P mus ncig ntawm lub voj voog ntawm lub vojvoog 1. Cov sib thiab cov cosine rov ua lawv cov txiaj ntsig ntawm lub sijhawm tsis tu ncua.
Tsis tas li ntawd, qhov sib txawv ntawm lub voj voog ua haujlwm thiab cov haujlwm trigonometric yog dab tsi?
Qhov twg trigonometric muaj nuj nqi muaj cov domains uas yog pawg ntawm cov ces kaum thiab ntau yam uas yog tus lej tiag, ncig ua haujlwm muaj cov domains uas yog pawg ntawm cov zauv uas sib haum mus rau lub kaum sab xis ntawm lub trigonometric muaj nuj nqi (hauv radians).
Ib yam li ntawd, 6 lub voj voog ua haujlwm yog dab tsi? Lub rau lub ntsiab trigonometric functions yog sib , cosine , tangent, secant , cosecant , thiab cotangent.
Nyob rau hauv no hais txog, dab tsi yog lub voj voog thiab trigonometry?
Trigonometric muaj nuj nqi txhais tau tias lawv cov npe yog pawg ntawm cov ces kaum thiab lawv qhov ntau yog cov lej tiag. Lub voj voog ua haujlwm txhais tau hais tias lawv cov npe yog cov lej uas sib haum rau kev ntsuas (hauv radian units) ntawm cov ces kaum ntawm analogous trigonometric muaj nuj nqi.
Vim li cas trigonometric functions yog periodic?
Muaj ntau qhov xwm txheej uas ntau tshaj ib lub kaum sab xis muaj tus nqi tib yam rau nws sib , cosine, los yog lwm yam trigonometric muaj nuj nqi . Qhov tshwm sim no tshwm sim vim txhua yam trigonometric functions yog periodic . A ua haujlwm raws sijhawm yog a muaj nuj nqi uas qhov tseem ceeb (tso tawm) rov ua dua nyob rau hauv ib ntus.

Yuav ua li cas koj multiply composite functions?
Multiplication and Composition of Functions Yuav kom muab ntau txoj haujlwm los ntawm tus lej, muab txhua qhov tso tawm los ntawm qhov ntsuas ntawd. Thaum peb coj f (g(x)), peb muab g(x) raws li cov tswv yim ntawm kev ua f. Piv txwv li, yog f (x) = 10x thiab g(x) = x + 1, ces nrhiav f (g(4)), peb nrhiav g(4) = 4 + 1 + 5, thiab ces ntsuas f (5. ) = 10(5) = 50. Example: f(x) = 2x - 2, g(x) = x2 - 8
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Cov hluav taws xob mus ncig ib puag ncig yooj yim li cas?
Cov khoom uas nqa cov nqi ntawm cov xov hlau hauv ib lub voj voog yog cov khoom siv hluav taws xob mobile. Kev taw qhia hluav taws xob hauv ib lub voj voog yog los ntawm kev txhais cov kev taw qhia uas cov nqi kuaj tau raug thawb. Yog li, cov electrons tsis zoo no txav mus rau hauv cov kev taw qhia opposite lub teb hluav taws xob
Dej hiav txwv ncig ua haujlwm li cas?
Cov dej hiav txwv dej hiav txwv tau tsav los ntawm ntau qhov chaw: cua, dej ntws, kev hloov pauv hauv dej, thiab kev sib hloov ntawm lub ntiaj teb. Qhov saum toj kawg nkaus ntawm cov dej hiav txwv hauv pem teb thiab ntug dej hiav txwv hloov cov kev taw qhia, ua rau cov dej ntws nrawm nrawm, qeeb qeeb, lossis hloov cov kev taw qhia
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
