Ua raws li qhov no hauv kev xav, koj ua li cas nco txog trig functions?
Yuav ua li cas nco cov ntsiab lus ntawm trig functions
- Soh. Soh - sine, opposite tshaj hypotenuse. sin(θ) = oppositehypotenuse.
- Cah. Cah - cosine, nyob ib sab ntawm hypotenuse. cos(θ) = adjacenthypotenuse.
- Toa. Toa - tangent, opposite tshaj nyob ib sab. tan(θ) = luas.
Ib sab saum toj no, kuv yuav tsum tau sau dab tsi rau kev suav lej? Tej Yam Tseem Ceeb Yuav Me Me rau Calculus
- Daim Ntawv Pov Thawj.
- Cofunction Identities.
- Quotient Identities.
- Pythagorean Identities.
- Ob lub kaum ntse ntse.
- Odd-Even Identities.
- Sum thiab Difference Identities.
- Half Angle Identities.
Tib neeg kuj nug, dab tsi yog qhov derivative ntawm arcsin?
y = arcsin (x). sin(y) = sin( arcsin (x)) = x. Tom ntej no, sib txawv ob qhov kawg ntawm cov qauv no. Peb siv txoj cai saw mus rau sab laug kawg, nco ntsoov tias qhov derivative ntawm lub sine muaj nuj nqi yog lub cosine muaj nuj nqi thiab hais tias y yog ib tug txawv muaj nuj nqi ntawm x.
y = arcsin (x) -1 x 1.
| d dx sin(y) | = | d d xwm |
|---|---|---|
| cos(y) dy dx | = | 1 |
Dab tsi yog chain rule hauv calculus?
Cov txoj cai saw hlau hais tias tus derivative ntawm f(g(x)) yog f'(g(x))⋅g'(x). Hauv lwm lo lus, nws pab peb sib txawv * kev ua haujlwm sib xyaw *. Piv txwv li, kev txhaum (x²) yog kev sib xyaw ua haujlwm vim nws tuaj yeem tsim ua f(g(x)) rau f(x) = sin(x) thiab g(x) = x².

Yuav ua li cas koj rho tus lej nrog tib lub cim?
Txhawm rau rho tawm cov lej, hloov cov cim ntawm tus lej uas yuav tsum tau rho tawm. Yog tias ob lub cim zoo, cov lus teb yuav zoo. Yog tias ob lub cim tsis zoo, cov lus teb yuav tsis zoo. Yog tias cov cim sib txawv rho tawm qhov tsawg dua qhov tseeb ntawm tus nqi loj dua
Yuav ua li cas koj nrhiav tau lub cim sawv cev ntawm ib tug quadratic muaj nuj nqi?
Quadratic functions tuaj yeem sawv cev los ntawm kev sib npaug, y(x) = ax2 + bx + c, qhov twg a, b, thiab c yog qhov tsis tu ncua, thiab a ≠ 0. Daim foos no raug xa mus rau daim ntawv qauv
Yuav ua li cas koj kwv yees cov pej xeem loj npaum li cas nyob rau hauv lub cim recapture txoj kev?
Cov txheej txheem Mark-Recapture yog siv los kwv yees qhov loj ntawm cov pej xeem uas nws ua tsis tau zoo los suav txhua tus neeg. Lub tswv yim tseem ceeb yog tias koj ntes cov tib neeg tsawg, muab lub cim tsis zoo rau lawv, thiab tso lawv rov qab rau hauv cov pej xeem
Vim li cas koj tig lub cim tsis sib xws thaum koj sib npaug lossis faib los ntawm qhov tsis zoo?
Thaum koj muab ob sab los ntawm tus nqi tsis zoo koj ua rau sab uas ntau dua muaj 'loj' tus lej tsis zoo, uas txhais tau tias tam sim no tsawg dua lwm sab! Qhov no yog vim li cas koj yuav tsum tig lub cim thaum twg koj muab los ntawm tus lej tsis zoo
Yuav ua li cas koj sau helium hauv cov cim cim?
Helium (los ntawm Greek: ?λ ι ο ς, romanized: Helios, lit. 'Sun') yog cov tshuaj lom neeg nrog lub cim Nws thiab tus lej atomic 2. Nws yog xim tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom. , inert, monatomic gas, thawj zaug nyob rau hauv cov pab pawg neeg noble nyob rau hauv lub periodic rooj
