Ib peb yog sib npaug rau feem: 1/3. Yog li ntawd, nws yog ib tug peb ntawm ib qho nyiaj. Peb yog xam los ntawm kev faib los ntawm 3.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj tau txais 1/3 ntawm tus lej?
1/3 txhais tau tias 1 ntawm 3 feem ntawm tag nrho. Yuav txheeb xyuas dab tsi 1/3 ntawm ib yam dab tsi yog, koj technically muaj ob txoj kev xaiv: Faib los ntawm 3. Muab los ntawm 1/3 (uas yog tib yam)
Ib yam li ntawd, muaj pes tsawg halves nyob hauv 3? Muaj 6 ib nrab qhov loj me hauv 3 tag nrho. thiab peb tuaj yeem pom tias muaj 3 tag nrho nrog 2 ib nrab hauv txhua qhov, yog li muaj 3 imes 2 = 6 halves hauv 3.
Piv txwv li, 3rd ntawm 100 yog dab tsi?
1/3 x 100 = 33.33 Koj kuj yuav pom tias nws muaj txiaj ntsig kom paub tias yog koj muab 0.33 nrog 100 koj 33.33. Qhov ntawd txhais tau tias peb cov lus teb ntawm 33.33 yog 33.33 feem pua ntawm 100.
Qhov thib peb ntawm 42 yog dab tsi?
2/3 x 42 = 28.00 Koj kuj yuav pom tias muaj txiaj ntsig kom paub tias yog koj muab 0.67 nrog 100 koj tau 66.67. Qhov ntawd txhais tau tias peb cov lus teb ntawm 28.00 yog 66.67 feem pua 42.

Yuav ua li cas koj xam qhov hnyav thiab qhov sib npaug ntawm lub dav hlau?
Ntxiv tag nrho cov sijhawm mus nrhiav lub sijhawm tag nrho. Faib tag nrho lub sijhawm los ntawm qhov hnyav tag nrho kom pom qhov nruab nrab ntawm lub ntiajteb txawj nqus. Nrhiav tag nrho qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus daim ntawv qhia hauv koj lub dav hlau POH los txiav txim seb lub dav hlau puas nyob hauv qhov txwv
Yuav ua li cas koj nrhiav tau qhov thib ob derivative ntawm ib tug trig muaj nuj nqi?
VIDEO Tsuas yog li ntawd, dab tsi yog qhov derivatives ntawm 6 trig functions? Derivatives ntawm Trigonometric Functions. Lub hauv paus trigonometric functions suav nrog 6 lub luag haujlwm hauv qab no: sine ( kev txhaum x), cosine ( cos x), tangent (tanx), cotangent (cotx), secant (secx) thiab cosecant (cscx).
Peb puas tuaj yeem siv Newton txoj cai thib peb rau lub zog gravitational?
Yog lawm, Newton txoj cai thib peb yog siv tau rau lub zog gravitational. Yog li ntawd, qhov no txhais tau hais tias thaum peb lub ntiaj teb exerts ib lub zog ntawm attraction ntawm ib yam khoom, ces cov khoom kuj exerts ib tug sib npaug zog rau lub ntiaj teb, nyob rau hauv lub opposite direction. Yog li peb tuaj yeem hais tias koj tuaj yeem siv Newton txoj cai thib peb rau lub zog gravitational
Koj yuav daws qhov kev sib npaug thib ob li cas?
Kev daws 2nd Degree Equations ax2 + bx + c = 0 TheSquare-Root Method Siv txoj kev square-root yog tias tsis muaj lub sijhawm. Txhawm rau daws ax2 + bx + c = 0: 1st: Siv txoj kev square-rootmethod yog tias x-term ploj lawm. 2nd: Sim muab nws ua ob lub binomials. 3rd: Siv cov qauv plaub fab (QF)
Koj yuav daws li cas Newton txoj cai thib peb ntawm kev txav chaw?
Thaum twg ib lub cev tawm dag zog rau ntawm lub cev thib ob, thawj lub cev tau ntsib lub zog uas sib npaug ntawm qhov loj thiab rov qab mus rau lub zog uas nws tawm. Kev ua lej, yog tias lub cev A tawm dag zog → F ntawm lub cev B, ces B ib txhij ua lub zog − → F ntawm A, lossis hauv daim ntawv sib npaug vector, → FAB = − → FBA
