Cov thim rov qab cos, sec, thiab cot muaj nuj nqi yuav rov qab muaj nuj nqis hauv I thiab II Quadrants , thiab cov thim rov qab sin, csc, thiab tan muaj nuj nqi yuav rov qab muaj nuj nqis hauv I thiab IV Quadrants (tab sis nco ntsoov tias koj xav tau cov txiaj ntsig tsis zoo hauv Quadrant IV).

Ib yam li ntawd, tib neeg nug, dab tsi quadrants yog inverse kev txhaum?

Domain: x ∈ [−1, 1] Range: y ∈ [−π/2, π/2] (yog li lub kaum sab xis rau qhov inverse sine muaj nuj nqi ib txwm pom nyob rau hauv Quadrants I lossis IV) Kev txuas ntxiv: nruam rau txhua tus x hauv lub npe Kev nce-txo tus cwj pwm: nce Symmetry: khib (arcsin(−x) = − arcsin(x))) Boundedness: bounded saum toj thiab hauv qab Lub Zos Extrema: absolute max

yog Arcsin inverse ntawm kev txhaum? Cov arcsin function yog thim rov qab ntawm sine function. Nws rov qab lub kaum sab xis uas nws sine yog tus lej muab. Txhais tau tias: lub kaum sab xis uas kev txhaum yog 0.5 yog 30 degrees.

Kuj nug, qhov twg inverse trig functions txhais?

Cov inverse trigonometric muaj nuj nqi ua cov haujlwm sib txawv uas cov sine, cosine, tangent, secant, cosecant, thiab cotangent ua. Lawv raug siv los nrhiav qhov ntsuas ntawm lub kaum sab xis hauv daim duab peb sab yog thaum ob ntawm peb sab ntev paub.

Dab tsi yog qhov inverse ntawm cos?

arccos. Lub arccos muaj nuj nqi yog inverse ntawm tus cosine muaj nuj nqi. Nws rov lub kaum sab xis uas nws cosine yog tus lej muab.
