Rau ib 90 - degree kaum, multiply 90 los ntawm piv /180 tau piv /2. Los yog, yog tias koj muaj lub kaum sab xis ntawm 270 qib , koj yuav muab 270 los ntawm piv /180 rau 3 * piv / 2 radians.

Piv txwv li, 90 degree hauv ib lub voj voog yog dab tsi?

Cov Qib Cim: ° Peb siv me ntsis lub voj voog ° tom qab ntawd tus lej txhais tau tias qib . Piv txwv li 90 ° txhais tau tias 90 degrees.

Kuj Paub, koj yuav hloov cov degrees rau radians li cas ntawm pi? Rau Hloov ua lwm yam degrees rau radian , coj tus naj npawb ntawm qib yuav tsum tau hloov dua siab tshiab thiab muab nws los ntawm π/180. Koj tuaj yeem xam qhov no los ntawm hloov dua siab tshiab ob tus lej rau hauv feem. Piv txwv li, rau hloov 120 qib luas 120 x π/180 = 120π/180. Thaum koj tau txais koj cov lus teb, simplify lub radians.

Hauv qhov no, Pi hauv degrees yog dab tsi?

----------------------- Tom qab hloov kho - James Gay hais hauv nws cov lus teb, Pi tsis sib npaug ntawm tus lej qib vim piv tsis muaj unitis tsuas yog tus lej. Lub ntsiab lus yog qhov ntawd piv radians yog sib npaug rau 180 qib .”

Dab tsi yog 1 radian nyob rau hauv cov nqe lus ntawm pi?

Raws li tau hais, ib radian yog sib npaug rau 180 / π degree. Yog li ntawd, hloov los ntawm radians rau degrees, multiplyby 180/π. Conversely, hloov los ntawm degrees rau radians , muab faib ua π/180.
