Radiya

Ma'anar radiyo

Radian raka'a ce ta ma'aunin kusurwa. Juyin juyi na da'irar yana da kwana na 2π radians.

Radiyan shi ne na'urar ma'auni . Ana nuna ta ta hanyar alamar "rad" ko, ƙasa da yawa, ^c (don ma'aunin madauwari). Radian ya kasance ɗayan ƙarin SI, to amma an canza shi zuwa naúrar da aka samu a cikin shekara ta alif Dari Tara da casain da biyar 1995. Tsawon baka na radians yayi daidai da radiyan daga da'irar da yake sashi.

Amfani

Samfuri:Float box Yawancin mutanen da ke yin lissafi ko kimiyyar lissafi suna amfani da radians, maimakon digiri, saboda wasu nau'ikan lissafin, galibi a cikin trigonometry da ƙididdiga, sun fi sauƙi yayin amfani da radians maimakon digiri. Don haka, yawancin lissafin da ke da alaƙa da mitar angular (kamar saurin angular ) suna amfani da radians a sakan daya.

Mutanen da ke duba ta hanyar na'urar hangen nesa ko maharbi sukan yi amfani da milliradians don kwatanta nisa kamar yadda aka gani ta hanyarsa.

Juyawa

Radian 1 daidai yake da kusan 57.3°. Akwai radians 2 π (kimanin 6.28 radians) a cikin cikakken da'ira. Tsarin juya radian zuwa digiri da akasin haka shine:

$2\pi \text{ rad}=360^{\circ }$

$1\text{ rad}=\frac{360^{\circ }}{2\pi }=\frac{180^{\circ }}{\pi }\approx 57.29577951^{\circ }$

ko:

$360^{\circ }=2\pi \text{ rad}$

$1^{\circ }=\frac{2\pi }{360}\text{ rad}=\frac{\pi }{180}\text{ rad}\approx 0.01745329\text{ rad}$

kuma muna iya cewa:

$x\text{ rad}={\left(\frac{180x}{\pi }\right)}^{\circ }$ .
