Yog li ntawd, daim duab ntawm arctan(tanx) muaj qhov sau uas yog tag nrho ntawm x-axis tshwj tsis yog cov ntsiab lus uas x=(2n + 1) π2, thiab qhov ntau yog (−π2, π2), yog li Graph A qhia y=arctan(tanx).
Dab tsi yog qhov ntau ntawm arctan X?
Ntxiv ntxiv, tus sau ntawm arctan x=ntau ntawm tan x=(−∞, ∞) thiab ntau yam ntawm arctanx=domain ntawm tanx=(− π 2, π 2). Nco tseg: arctan(x) yog lub kaum sab xis hauv (− π 2, π 2) uas nws tangent yog x.
Arctan yog dab tsi ntawm x?
Arctan txhais
Lub arctangent ntawm x txhais tau tias yog inverse tangent ua haujlwm ntawm x thaum x yog tiag (x∈ℝ). Thaum lub tangent ntawm y yog sib npaug rau x: tan y=x. Ces lub arctangent ntawm x yog sib npaug rau inverse tangent function ntawm x, uas yog sib npaug rau y: arctan x=tan-1 x=y.
Arctan ntawm graphing tshuab xam zauv yog dab tsi?
The arctangent function is the inverse function of y=tan(x).
Arctan 1 hais txog pi yog dab tsi?
Tsuas π4 poob rau lub sijhawm no. Yog li, arctan1=π4.
