Tangent 30 degrees tus nqi yog ib los ntawm cag 3 (1/√3) Zoo li Sine thiab Cosine Sine thiab Cosine Sin 0 qhia tias tus nqi x kev tswj hwm yog 1 thiab tus nqi ntawm y kev tswj hwm yog 0, i.e. (x, y) yog (1, 0). Qhov ntawd txhais tau hais tias tus nqi ntawm qhov opposite sab los yog perpendicular yog xoom thiab tus nqi ntawm hypotenuse yog 1. https://byjus.com › maths › sin-0
Sin 0-Tus nqi ntawm Kev txhaum 0 degree thiab lwm yam kev ua haujlwm trigonometric - Byjus
Tangent kuj yog ib qho kev ua haujlwm ntawm trigonometry. Feem ntau ntawm cov kab zauv trigonometric yog raws li cov piv txwv no.
Koj pom tus nqi ntawm tan 30 li cas?
Vim lub tangent muaj nuj nqi yog lub sijhawm ua haujlwm, peb tuaj yeem sawv cev tan 30 ° li, tan 30 °=tan(30 ° + n × 180 °), n ∈ Z. ⇒ tan 30 °=tan 210 °=tan 390 °, thiab lwm yam. Nco tseg: Txij li thaum, tangent yog ib qho kev ua haujlwm khib, tus nqi ntawm tan(-30°)=- tan(30 °).
tan squared 30 yog dab tsi?
Trigonometry Piv txwv
Tus nqi tseeb ntawm tan(30) yog √33.
Can tan puas yog 0?
Nws tsuas yog lub tswv yim yooj yim ntawm trigonometry kom pom qhov sib npaug ntawm lub kaum sab xis siv lub sine thiab cosine ntawm lub kaum sab xis. Nws paub tias qhov piv ntawm sine thiab cosine ntawm tib lub kaum sab xis muab lub tangent ntawm tib lub kaum sab xis. … Yog li ntawd, tus Tan 0 yog sib npaug rau 0/1 lossis 0.
Tus nqi ntawm tan 30 lub hlwb yog dab tsi?
