Cia siv cosine muaj nuj nqi vim nws pib ntawm tus nqi siab tshaj lossis qis tshaj, thaum lub luag haujlwm sine pib ntawm tus nqi nruab nrab. Tus qauv cosine pib ntawm tus nqi siab tshaj plaws, thiab daim duab no pib ntawm tus nqi qis tshaj, yog li peb yuav tsum tau koom nrog qhov kev xav txog ntsug.
Puas Cos pib ntawm max lossis min?
Ib lo lus, lub cosine nkhaus pib ntawm nws qhov siab tshaj plaws lossis yam tsawg kawg nkaus. Cia peb saib y=cos x thiab tom qab ntawd peb mam li tham txog cov khoom ntawm cov haujlwm. Raws li koj tau pom, qhov nkhaus pib ntawm qhov siab tshaj plaws yog > 0.
Puas cosine pib 0?
The cosine function, \cos(x), pib ntawm 1 (ie, \cos(0)=1), yog li f(x) yuav tsum yog scaled version ntawm cosine muaj nuj nqi. Qhov muaj nuj nqi pib ntawm xoom (ie, f(0)=0), yog li ntawd nws zoo li cas?.
Puas Cos pib hauv qab?
Cosine zoo ib yam li Sine, tab sis nws pib ntawm 1 thiab nqes nqesmus txog π radians (180 °) thiab tom qab ntawd rov pib dua.
Niam txiv daim duab ntawm cosine pib qhov twg?
Ib yam li daim duab sine, koj siv tsib lub ntsiab lus tseem ceeb ntawm graphing trig functions kom tau tus niam txiv graph ntawm cosine muaj nuj nqi, f(x)=cos x. Yog tias tsim nyog, koj tuaj yeem xa mus rau chav tsev voj voog rau cov nqi cosine pib nrog.
Pom zoo:
Puas yog lactate qhov pib zoo ib yam li qhov pib anaerobic?
Anaerobic Threshold (AT) yog ib lo lus siv rau lub cev tsis muaj zog lactate, lossis lub ntsiab lus ntawm qhov pom ntawm lactate hauv cov ntshav accumulates sai dua uas nws qhov kev siv. … Lactate Threshold (LT) yog ib lo lus tsis ntev los no thiab piav qhia txog cov ntsiab lus lactate inflection tau piav saum toj no.
