Ntau: Muaj ntau lub ces kaum uas muaj cov cotangent sib npaug li 1. Peb nug tiag tiag "dab tsi yog qhov yooj yim tshaj plaws, feem ntau lub kaum sab xis uas muaj cov cotangent sib npaug rau 1?" Raws li ua ntej, cov lus teb yog 45 °. Yog li cot-1 1=45° los yog cot- 1 1=π/4.
Puas yog cotangent tib yam li 1 tangent?
Peb paub tias cotangent yog qhov sib cuam tshuam ntawm tangent. Txij li thaum tangent yog qhov piv ntawm qhov sib txawv rau qhov nyob ib sab, cotangent yog qhov piv ntawm qhov nyob ib sab mus rau qhov opposite.
Vim li cas cov cotangent tsis tau txhais?
Trigonometric functions tsis tau txhais thaum lawv sawv cev feem nrog tus lej sib npaug rau xoom. Cotangent yog qhov sib txuam ntawm tangent, yog li lub cotangent ntawm txhua lub kaum x rau qhov twg tan x=0 yuav tsum tsis tau txhais, vim nws yuav muaj tus lej sib npaug rau 0.
cotangent sib npaug rau qhov twg?
Nyob rau hauv ib lub kaum sab xis, lub cotangent ntawm lub kaum sab xis yog: Qhov ntev ntawm sab uas nyob ib sab faib los ntawm qhov ntev ntawm sab opposite lub kaum sab xis.
cotangent ntawm theta sib npaug li cas?
Lub luag haujlwm tangent yog cotangent, qhia ob txoj hauv kev: cot(theta)=1/tan(theta) los yog cot(theta)=cos(theta)/sin(theta).
Pom zoo:
Los ntawm cov khoom sib npaug ntawm kev sib npaug?
Cov cuab yeej sib luag ntawm kev sib luag hauv paus hais uas ob sab ntawm kev sib npaug yog tib yam. Qhov no ua rau kev txiav txim siab vim tias thaum ib yam dab tsi sib luag, nws yog tib yam ntawm ob sab. Cov cuab yeej sib luag ntawm kev sib npaug tso cai rau sab laug ntawm qhov sib npaug los ua sab xis thiab rov ua dua.
Puas yog cov nqi sib npaug sib npaug?
Kev sib npaug ntawm thaj av, zoo li kev them nyiaj tshaj ib feem ntawm thaj av, tuaj yeem hla dhau raws li txoj cai yog tias muaj kev muag khoom raws li txoj cai. Puas yog tus nqi sib npaug yog tus nqi sau npe? Tus nqi sib npaug tsis tuaj yeem sau npe rau ntawm nws tus kheej txoj cai thiab yuav tsum tau tiv thaiv los ntawm kev nkag mus rau hauv daim ntawv ceeb toom.
Puas trs cables sib npaug lossis tsis sib npaug?
TRS cables tuaj yeem siv rau mono, ntsuas cov cim ntsuas nrog rau cov cim tso suab. Ib qho piv txwv ntawm mono, cov teeb liab sib npaug yuav yog kab tawm tswv yim lossis cov zis tawm los ntawm cov khoom sib tov lossis lub suab interface. Lub mloog pob ntseg tau txais cov cim tso suab ntawm TRS cables.
Puas yog sib npaug thiab sib npaug?
yog qhov sib npaug yog qhov xwm txheej ntawm qhov kev sib tw uas muaj kev sib tw sib npaug, ua rau tsis muaj qhov hloov pauv thaum sib npaug yog ib lub zog sib npaug, tab sis ntxeev ntawm, qhov tshwm sim sum ntawm vector zog; lub zog uas sib npaug rau lwm lub zog, yog li nqa ib qho khoom mus rau qhov sib npaug.
Puas muaj qhov sib npaug sib npaug?
Ib kab kab sib npaug feem ntau muaj ib qho kev daws teeb meem, tab sis qee zaum nws tsis tuaj yeem muaj kev daws teeb meem (kab kab sib txuas) lossis kev daws tsis kawg (ib kab). Kab lus no tshuaj xyuas tag nrho peb qhov xwm txheej. Ib qho kev daws teeb meem.
