Cov derivative tuaj yeem muab koj tus nqi ncaj nraim rau qhov kev hloov pauv ntawd thiab ua rau kev ua qauv zoo ntawm qhov xav tau kom muaj nuj nqis. Cov ib qho ntawm ib qho kev ua haujlwm tuaj yeem txhais geometrically raws li thaj tsam hauv qab ntawm qhov nkhaus ntawm kev ua lej f(x) plotted raws li kev ua haujlwm ntawm x.

Piv txwv li, qhov sib txawv ntawm qhov sib xyaw thiab cov khoom siv yog dab tsi?

Derivative yog qhov tshwm sim ntawm cov txheej txheem sib txawv, thaum ib qho yog qhov tshwm sim ntawm cov txheej txheem kev koom ua ke . Derivative ntawm ib qho kev ua haujlwm sawv cev rau txoj kab nqes ntawm qhov nkhaus ntawm txhua qhov chaw, thaum ib qho sawv cev rau thaj tsam hauv qab qhov nkhaus.

yog ib qho integral Qhov opposite ntawm ib tug derivative? Nyob rau hauv calculus, ib ib qho yog qhov chaw nyob rau hauv ib daim duab ntawm ib qho kev sib npaug (qee zaum hais tias "qhov chaw nyob rau hauv ib qho nkhaus"). Ib ib qho yog qhov rov qab ntawm a derivative thiab yog cov rov qab ntawm qhov sib txawv calculus. Qhov kev sib txuas ntawm ob qho no tseem ceeb heev, thiab hu ua Fundamental Theorem of Calculus.

Ib yam li ntawd, qhov derivative ntawm ib qho tseem ceeb txhais li cas?

ces cov derivative ntawm F(x) yog F'(x) = f(x) rau txhua x hauv lub caij nyoog I. Qhov xaus ntawm lub hauv paus theorem ntawm kev suav lej ua tau yuav loosely qhia nyob rau hauv cov lus raws li: "the derivative ntawm ib qho integral ntawm ib txoj haujlwm yog qhov kev ua haujlwm qub", lossis "kev sib txawv tsis ua raws li kev sib koom ua ke".

Lub hom phiaj ntawm integral yog dab tsi?

Kev koom ua ke yog ib txoj hauv kev ntxiv cov hlais kom pom tag nrho. Kev koom ua ke tuaj yeem siv los nrhiav thaj chaw, ntim, nruab nrab cov ntsiab lus thiab ntau yam tseem ceeb. Tab sis nws yog qhov yooj yim tshaj plaws los pib nrog kev nrhiav thaj chaw hauv qab ntawm qhov nkhaus ntawm a muaj nuj nqi zoo li no: thaj tsam hauv qab y = f(x) yog dab tsi?
