Rau xam tus inverse log ntawm tus lej hauv thawj ob qhov xwm txheej, tsa lub hauv paus rau lub zog ntawm tus nqi rov qab los ntawm qhov tshwj xeeb logarithm muaj nuj nqi siv. Nrhiav qhov thim rov qab ntuj log , siv EXPfunction.
Nyob rau hauv kev hwm rau qhov no, ua li cas koj nrhiav tau qhov inverse ntawm lub cav?
Cov kauj ruam los nrhiav qhov Inverse ntawm Logarithm
- Kauj Ruam 1: Hloov cov ntawv sau ua haujlwm f (x) los ntawm y.
- Kauj ruam 2: Hloov lub luag haujlwm ntawm x thiab y.
- x → y.
- y → x.
- KAUJ RUAM 3: cais cov lus qhia ntawm ib sab (sab laug lossis sab xis) ntawm qhov sib npaug.
- KAUJ RUAM 5: daws qhov kev sib npaug exponential rau "y" kom tau qhov rov qab.
Ib tug kuj nug, Antilog mis yog dab tsi? Antilog = Inverse Log The antilogarithm yog inverse muaj nuj nqi ntawm lub logarithm, log(b) x = y txhais tau tias antilog (b) y = x. Koj sau qhov no nrog exponential notation li ntawd antilog (b) y = x implies by = x.
Ib sab saum toj no, koj ua li cas suav cov log hauv Excel?
Excel LN Function
- Cov ntsiab lus. Excel LN muaj nuj nqi xa rov qab cov logarithm ntuj ntawm tus lej muab.
- Tau txais lub ntuj logarithm ntawm tus lej.
- Lub ntuj logarithm.
- = LN (npe)
- tus lej - Ib tus lej coj tus lej logarithm ntawm.
- Lub ntuj logarithm muaj nuj nqi yog qhov sib npaug rau lub hauv paus eof tus lej. Qhov twg e yog Euler tus lej.
Log muaj nuj nqi hauv Excel yog dab tsi?
Lub Microsoft Excel LOG muaj nuj nqi rov qab thelogarithm ntawm tus lej mus rau lub hauv paus. Cov LOG muaj nuj nqi yog ib tug built-in ua haujlwm hauv Excel uas yog categorized li aMath/Trig Muaj nuj nqi . Raws li daim ntawv ua haujlwm muaj nuj nqi , cov LOG muaj nuj nqi tuaj yeem nkag mus ua ib feem ntawm cov qauv hauv cellof ib daim ntawv ua haujlwm.

Yuav ua li cas koj xam qhov muaj peev xwm poob hauv ib lub voj voog?
Voltage poob: Parallel Circuit Qhov no txhais tau hais tias qhov hluav taws xob poob thoob plaws txhua qhov tsuas yog tag nrho qhov hluav taws xob ntawm lub voj voog muab faib los ntawm tus lej ntawm cov resistors hauv Circuit Court, lossis 24 V / 3 = 8 V
Kuv yuav xam pes tsawg tus neeg txhais li cas hauv Excel?
Population Mean = Sum of All the Items / Number of Items Population Mean = (14+61+83+92+2+8+48+25+71+12) / 10. Population Mean = 416 / 10. Population Txhais = 41.6
Yuav ua li cas xam CV hauv Excel?
Yuav ua li cas thiaj nrhiav tau tus coefficient ntawm kev hloov pauv hauv Excel.Koj tuaj yeem suav cov coefficient ntawm kev hloov pauv hauv Excel siv cov qauv rau tus qauv sib txawv thiab txhais tau tias.Rau ib kab ntawm cov ntaub ntawv (ie A1: A10), koj tuaj yeem nkag mus: “=stdev(A1: A10) / nruab nrab (A1: A10)) tom qab ntawd muab faib ua 100
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
