Umsebenzi we-Trigonometric: I-Sine ye-engeli (isono)

Incazelo

I-Sine ye-engeli e-acute α (ngaphandle α) isilinganiso somlenze ophambene (ai-hypotenuse (c) kunxantathu ongakwesokudla.

ngaphandle α = a / c

Ngokwesibonelo:

a = 3

c = 5

ngaphandle α = a / c = 3/5 = 0.6

Umsebenzi wesine ubhalwe ngokuthi y = ngaphandle (x). Igrafu ibizwa i-sinusoid futhi ngokujwayelekile kubonakala kanje:

Umsebenzi we-Trigonometric: Umugqa we-engeli (isono)

I-sinusoid umsebenzi wezikhathi ezithile onenkathi T = 2π.

Ngezansi kufomu lethebula izici eziyinhloko ze-sine namafomula:

Обратная к синусу функция

– это обратная функция к синусу x, isiqephu -1≤x≤1.

Если синус угла у kuyalingana х (Isono y = x), значит арксинус x ilingana ne у:
