Txhawm rau kos duab tag nrho niam txiv daim duab ntawm cotangent, ua raws li cov kauj ruam no:

  1. Nrhiav cov asymptotes ntsug kom koj tuaj yeem nrhiav tau tus sau.
  2. Nrhiav cov nqi rau qhov ntau.
  3. Txiav txim siab x-intercepts.
  4. 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:

  1. Sketch daim duab ntawm y = sin x ntawm −4π rau 4π, raws li qhia hauv daim duab no.
  2. Kos cov asymptotes ntsug los ntawm x-intercepts, raws li cov duab hauv qab no qhia.
  3. 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.

  1. Nrhiav qhov y-intercept ntawm daim duab thiab npaj lub ntsiab lus.
  2. Txij ntawm no mus, siv txoj kab nqes los nrhiav qhov thib ob thiab teeb tsa nws.
  3. 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.
