Cov haujlwm tangent thiab secant, piv txwv li, yog undefined thaum tus nqi cosine yog 0. Ib yam li ntawd, tus nqi cotangent thiab cosecant tsis tau txhais thaum tus nqi sine yog 0.
Yuav ua li cas thaum tan tsis tau txhais?
Teb thiab piav qhia: Lub tangent muaj nuj nqi, tan(x) yog undefined thaum x=(π/2) + πk, qhov twg k yog tus lej.
Qhov twg tangent undefined?
Vim, tan(x)=sin(x)cos(x) tangent function is undefined when cos(x)=0. Yog li ntawd, tangent muaj nuj nqi muaj ib tug ntsug asymptote thaum twg cos(x)=0. Ib yam li ntawd, cov tangent thiab sine ua haujlwm txhua tus muaj pes tsawg ntawm qhov sib npaug ntawm π vim tan(x)=0 thaum sin(x)=0.
Vim li cas tan undefined ntawm 90 thiab 270?
Thaum 90 degrees peb yuav tsum hais tias qhov tangent tsis tau txhais (und), vim thaum koj faib txhais ceg rov qab los ntawm ceg uas nyob ib sab koj tsis tuaj yeem faib los ntawm xoom. … Ntawm 270 degrees peb rov muaj qhov tsis tau txhais (und) tshwm sim vim peb tsis tuaj yeem faib los ntawm xoom..
Vim li cas tan ntawm 90 degrees tsis tau txhais?
tan90∘ is undefined vim koj faib tsis tau 1 los tsis muaj dab tsi. Tsis muaj dab tsi muab faib los ntawm 0 yuav muab cov lus teb ntawm 1, yog li cov lus teb tsis tau txhais.

Ntawm twg ntawm cov ces kaum hauv qab no yog cov haujlwm cotangent tsis tau txhais?
Trigonometric functions tsis tau txhais thaum lawv sawv cev cov feem nrog cov zauv sib npaug rau xoom. Cotangent yog qhov sib txuam ntawm tangent, yog li cov 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 .
