Piv txwv 1: daws:
- Nkag mus rau sab laug hauv Y1. Koj nrhiav tau abs () sai sai nyob rau hauv CATALOG (saum toj no 0) (los yog MATH → NUM, #1 abs ()
- Nkag mus rau sab xis hauv Y2.
- Siv Txoj Kev Xaiv Sib Tham (2nd CALC #5) txhawm rau nrhiav qhov twg daim duab sib tshuam. Txav tus kab laug sab ze ntawm qhov chaw ntawm kev sib tshuam, nias ENTER.
- Teb: x = 4; x = -4.
Tsis tas li cov lus nug yog, koj ua li cas thiaj nrhiav tau tus nqi ntawm TI 84?
Koj ua tau nrhiav tus tus nqi kiag hais kom ua los ntawm nias [math] thiab mus rau sab xis ib tab. (Nws hais tias NUM) Nws yuav tsum yog thawj tus ntawm cov npe.
Tsis tas li ntawd, koj sau tus nqi kiag li cas? Typing cov Tus nqi tsis txaus Kos npe rau feem ntau cov keyboards hauv computer, koj tuaj yeem pom qhov "|" cim saum lub backslash, uas zoo li "". Rau hom nws, tsuas yog tuav tus yuam sij hloov thiab ntaus tus yuam sij backslash.
Kuj kom paub yog, ua li cas koj muab tus nqi kiag rau hauv lub laij lej?

Tus nqi ntawm 20 yog dab tsi?
| 20 | = 20 ; Tus nqi tsis txaus ntawm 20 yog 20.

Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Koj ntsuas tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed li cas?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
Ib coulomb ib ob
Koj ntsuas tus nqi ntawm enzyme ua haujlwm li cas?
Enzyme assay Enzyme assay yog txoj hauv kev kuaj rau kev ntsuas kev ua haujlwm enzymatic. Qhov kom muaj nuj nqis lossis concentration ntawm ib qho enzyme tuaj yeem qhia tau nyob rau hauv cov nyiaj molar, xws li nrog rau lwm yam tshuaj, lossis hais txog kev ua haujlwm hauv enzyme units. Kev ua enzyme = moles ntawm substrate hloov dua siab tshiab rau ib chav tsev lub sij hawm = tus nqi × cov tshuaj tiv thaiv ntim
