cosecant is the reciprocal of the sine. Nws yog qhov piv ntawm hypotenuse rau sab opposite ib lub kaum sab xis muab rau hauv ib daim duab peb sab.
CSC puas nrog kev txhaum?
Lub secant ntawm x yog 1 faib los ntawm cov cosine ntawm x: sec x=1 cos x, thiab cov cosecant ntawm x txhais tau tias yog 1 faib los ntawm sine ntawm x: csc x=1 sin x.
Puas cosecant tshem tawm sine?
Qhov sib txuam ntawm sine muaj nuj nqi yog qhov ua haujlwm cosecant. Cov hauv qab no yog tus kheej siv tau rau txhua tus x hauv lub npe ntawm cov haujlwm cosecant. Qhov kev ua haujlwm arcsine yog qhov ua haujlwm rov qab rau qhov kev ua haujlwm sine ntawm lub sijhawm. Yog li lawv "tso tseg" ib leeg hauv kev ua haujlwm ntawm kev ua haujlwm, raws li hauv qab no.
Puas yog cosecant tib yam li kev txhaum 1?
Yog li tus reciprocal ntawm sine muaj nuj nqi yog hu ua cosecant thiab sib npaug rau lub hypotenuse / opposite. … Qhov kev ua haujlwm cosecant txhais tau tias 1 / kev txhaum θ, thaum qhov thib ob suav nrog kev nrhiav lub kaum sab xis uas nws yog x.
sine thiab cosecant graphs cuam tshuam li cas?
Cosecant yog qhov sib txuam ntawm sine, lossis \begin{align}\frac{1}{y}\end{align}. Yog li ntawd, thaum twg lub sine yog xoom, lub cosecant yuav muaj ib tug ntsug asymptote vim nws yuav undefined. Nws kuj muaj tib lub cim raws li sine muaj nuj nqi hauv tib lub quadrants. Nov yog daim duab.
