Qhov tseeb, tus nqi xa rov qab los ntawm kev ua haujlwm cosecant rau lub kaum sab xis ntawm xoom degrees lossis ib puas yim caum degrees yog suav tias yog tsis tau txhais, txij li qhov sib npaug csc (θ)=1/sinθ) yuav suav nrog kev faib los ntawm xoom. Tib yam muaj tseeb rau kaum peb puas rau caum degrees (360°).
Lub kaum twg yog cosecant undefined?
Trigonometric functions tsis tau txhais thaum lawv sawv cev cov feem nrog tus lej sib npaug rau xoom. Cosecant yog reciprocal ntawm sine, yog li tus cosecant ntawm ib lub kaum x rau qhov twg sin x=0 yuav tsum tau undefined, vim nws yuav muaj ib tug denominator sib npaug zos rau 0. Tus nqi ntawm kev txhaum (0) yog 0, yog li cov cosecant ntawm 0 yuav tsum. yuav undefined.
Vim li cas csc 180 undefined?
csc(180°)=1sin(180°)=10. Vim peb faib los ntawm 0, nws tsis tau txhais. … Qhov "sab sab nraud" ntawm daim duab peb sab no tsis muaj, yog li peb hu qhov no cosecant undefined.
Rau qhov twg tus nqi ntawm theta yog csc undefined?
csc(θ) tsis tau txhais ntawm θ=0, θ=π thiab θ=2π, txawm li cas los xij peb tuaj yeem tau txais cov ntaub ntawv hais txog tus cwj pwm csc(θ) ze rau cov txiaj ntsig no siv lub claculator.
Qhov twg ntawm cov ces kaum hauv qab no yog Secant ua haujlwm tsis tau txhais?
Qhov tseeb, tus nqi rov qab los ntawm kev ua haujlwm secant rau ib lub kaum sab xis ntawm cuaj caum degrees lossis ob puas thiabxya caum degrees yog suav tias yog undefined, txij li qhov sib npaug sec (θ)=1/cos( θ) yuav suav nrog kev faib los ntawm xoom.

Ntawm twg ntawm cov ces kaum hauv qab no yog cov haujlwm secant tsis tau txhais?
Qhov tseeb, tus nqi xa rov qab los ntawm kev ua haujlwm secant rau ib lub kaum sab xis ntawm cuaj caum degrees lossis ob puas thiab xya caum degrees yog suav tias yog tsis tau txhais, txij li qhov sib npaug sec (θ)= 1 / cos θ ) yuav suav nrog kev faib los ntawm xoom.
Qhov twg hauv qab no yog qhov piv txwv ntawm qhov tsis suav nrog cov lej tsis suav nrog?
Pi is a non-terminating, non-repeating decimal. π=3.141 592 653 589 793 238 462 643 383 279 … e is a non-terminating, non-repeating decimal. Ib qho piv txwv ntawm tus lej tsis suav nrog yog dab tsi? Piv txwv: 0.5, 2.456, 123.456, thiab lwm yam.
Cov ces kaum twg yog cov ces kaum nyob ib sab?
cov ces kaum uas nyob ib sab yog ob lub ces kaum uas muaj ib qho vertex thiab ib sab tab sis tsis sib tshooj. Hauv daim duab, ∠1 thiab ∠2 yog cov kaum sab xis. Lawv sib koom tib lub vertex thiab tib yam sab. Lub kaum twg nyob ib sab? Yog ob lub ces kaum sib koom ib sab thiab ob qho tib si muab los ntawm tib lub ces kaum (vertex) taw tes, ces lawv yog cov ces kaum nyob ib sab.
