tan θ ≈ θ ntawm txog 0.1730 radians (9.91°) sin θ ≈ θ ntawm txog 0.2441 radians (13.99°) cos θ ≈ 1 − θ 2^{2 ntawm 0.6620 radians (37.93°)}

Vim li cas tan theta sib npaug rau theta?

Tangent theta sib npaug sab opposite theta muab faib los ntawm sab uas nyob ib sab ntawm theta Yog li no yog theta. Tangent theta yog qhov ntev muab faib los ntawm qhov ntev lossis y tshaj x. Tab sis qhov kev txhais no tsuas yog ua haujlwm rau cov kaum sab xis, lub kaum sab xis ntawm 0 thiab 90 degrees, vim tias nws tsuas yog txhais txoj hauv kev no ntawm txoj cai daim duab peb sab.

Kev sib raug zoo ntawm tan theta thiab sin theta yog dab tsi?

Kev sib raug zoo ntawm cov trigonometric tus kheej nrog ob sab ntawm daim duab peb sab tuaj yeem muab tau raws li hauv qab no: Sine (theta)=Opposite/Hypotenuse . Cos (theta)=Adjacent/Hypotenuse . Tan (theta)=Rov qab/Adjacent.

Dab tsi yog sin theta formula?

Sine Function: sin(θ)=Rov qab / Hypotenuse. Cosine Function: cos(θ)=Adjacent / Hypotenuse.

Tus qauv ntawm tan theta yog dab tsi?

The formula for tan 2x identity is given as: tan 2x=2tan x / (1−tan²x) tan 2x=sin 2x/cos 2x.
