Txhawm rau kos duab tag nrho niam txiv daim duab ntawm cotangent, ua raws li cov kauj ruam no:
- Nrhiav cov asymptotes ntsug kom koj tuaj yeem nrhiav tau tus sau.
- Nrhiav cov nqi rau qhov ntau.
- Txiav txim siab x-intercepts.
- Ntsuas seb yuav ua li cas rau qhov daim duab nruab nrab ntawm x-intercepts thiab asymptotes.
Yog li ntawd, koj yuav ua li cas rau daim duab CSC?
Txhawm rau graph y = csc x, ua raws li cov kauj ruam no:
- Sketch daim duab ntawm y = sin x ntawm −4π rau 4π, raws li qhia hauv daim duab no.
- Kos cov asymptotes ntsug los ntawm x-intercepts, raws li cov duab hauv qab no qhia.
- Kos y = csc x nruab nrab ntawm cov asymptotes thiab nqes mus rau (thiab nce mus rau) sine nkhaus, raws li qhia hauv daim duab hauv qab no.
Tom qab ntawd, lo lus nug yog, koj ua li cas kos duab? Txhawm rau kos ib kab zauv sib npaug, peb tuaj yeem siv txoj kab nqes thiab y-intercept.
- Nrhiav qhov y-intercept ntawm daim duab thiab npaj lub ntsiab lus.
- Txij ntawm no mus, siv txoj kab nqes los nrhiav qhov thib ob thiab teeb tsa nws.
- Kos cov kab uas txuas ob lub ntsiab lus.
Hais txog qhov no, dab tsi yog Cotangent ntawm lub tshuab xam zauv?
Hauv trigonometry, lub cotangent yog qhov sib txuam ntawm tangent. Thaum nkag cotangent mus rau hauv graphing tshuab xam zauv , koj yuav tsum paub lub kaum sab xis nyob rau hauv degrees uas koj tab tom sim nrhiav tus cotangent . Ntaus "1" rau hauv koj daim duab tshuab xam zauv . Nias lub npe faib.
Secant yog dab tsi inverse?) (sec) (sec) Lub secant yog cov reciprocal ntawm cov cosine. Nws yog qhov piv ntawm lub hypotenuse rau sab uas nyob ib sab mus rau lub kaum sab xis muab rau hauv ib daim duab peb sab.

Dab tsi yog cov cim siv hauv daim duab kos duab?
Schematic Symbols Wires (Txuas Txuas) Cov cim no sawv cev rau kev sib koom hluav taws xob sib txuas ntawm ob yam khoom. Hlau (tsis txuas) DC Supply Voltage. Hauv av. Tsis muaj kev sib txuas (nc) Resistor. Capacitor, Polarized (Electrolytic) Lub teeb-Emitting Diode (LED)
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi yog lub ntsiab lus ntawm kev kos duab kos duab?
DefinitionEdit 'Concept maps yog graphical tools for organize and representing knowledge. Lawv suav nrog cov ntsiab lus, feem ntau yog kaw rau hauv lub voj voog lossis lub thawv ntawm qee hom, thiab kev sib raug zoo ntawm cov ntsiab lus qhia los ntawm ib txoj kab sib txuas txuas ob lub tswv yim
