Cov sinusoidal axis yog txoj kab nruab nrab kab rov tav uas nyob nruab nrab ntawm cov crests thiab cov troughs (los yog ncov thiab hav yog tias koj nyiam).

Xav txog qhov no, qhov sib npaug ntawm sinusoidal axis yog dab tsi?

Sau a sib muaj nuj nqi koj tsuas yog yuav tsum tau siv cov hauv qab no kev sib npaug : f (x) = asin(bx + c) + d, qhov twg a yog qhov amplitude, b yog lub sijhawm (koj tuaj yeem pom lub sijhawm los ntawm kev faib tus nqi kiag li b los ntawm 2pi; hauv koj rooj plaub, Kuv ntseeg tias qhov zaus thiab lub sijhawm yog tib yam), c yog qhov hloov pauv theem (lossis hloov raws li x- axis

Kuj Paub, yog cosine ib sinusoidal? Yog, ib qho sib muaj nuj nqi tuaj yeem sawv cev los ntawm a cosine ua haujlwm nrog kev hloov pauv ntawm pi / 2. Thiab txhua txoj haujlwm cos tuaj yeem sawv cev los ntawm kev ua txhaum nrog kev hloov pauv ntawm pi / 2.

Hauv qhov no, daim duab sinusoidal yog dab tsi?

A sinusoidal muaj nuj nqi yog ib tug muaj nuj nqi uas zoo li ib tug sine muaj nuj nqi nyob rau hauv lub siab hais tias lub functionality yuav ua tau los ntawm kev hloov, stretching los yog compressing lub sine muaj nuj nqi. Yog tias tsim nyog koj tuaj yeem xav tshuaj xyuas cov daim duab luv luv.

Dab tsi yog qhov axis ntawm qhov nkhaus?

Kev txhais ntawm axis ntawm a nkhaus .: ib txoj kab ncaj nraim uas bisects ntawm txoj cai kaum ib qhov system ntawm parallel chords thiab faib cov nkhaus rau hauv ob feem symmetrical (xws li nyob rau hauv parabola uas muaj ib qho xws li axis , lub ellipse uas muaj ob, lossis lub voj voog uas muaj tus lej tsis kawg)
