Kev Siv Calculus Hauv Kev Tsim Kho Tshuab Calculus yog ib ceg tseem ceeb ntawm kev suav lej hauv kev tsim kho tshuab, suav nrog kev tsim kho tshuab. Yuav luag txhua qhov xwm txheej uas tau kawm hauv kev tsim kho tshuab - los ntawm kev txav mus los thiab lub zog mus rau kev hloov pauv cua sov thiab cov kua dej ntws mus rau kev co - cuam tshuam nrog kev hloov pauv tas mus li. Vim tias calculus tsom mus rau cov tswv yim ntawm kev hloov pauv (qhov sib txawv) thiab kev sib sau ua ke (kev sib xyaw), nws yog hom lus tseem ceeb ... nyeem ntxiv
Kev Hloov Laplace hauv Cov Qauv Kev hloov Laplace yog ib qho cuab yeej lej tseem ceeb rau kev tshuaj xyuas thiab daws ntau hom qauv, tshwj xeeb yog cov qauv sib txawv. Cov txheej txheem no siv dav hauv kev tsim kho, physics, kev tswj hwm, cov voj voog hluav taws xob, thiab kev tsim qauv dynamics vim nws tuaj yeem hloov cov teeb meem nyuaj hauv lub sijhawm sau mus rau hauv cov teeb meem yooj yim dua hauv… nyeem ntxiv
Kab zauv Hyperbola hauv Geometry: Hyperbola yog ib qho ntawm cov kab nkhaus tseem ceeb tshaj plaws hauv kev tshuaj xyuas geometry, nrog rau lub voj voog, ellipse, thiab parabola. Cov kab nkhaus no feem ntau tshwm sim hauv kev lej ntshiab thiab kev siv, xws li kev taug kev, kev kawm txog hnub qub, thiab physics. Yuav kom nkag siab txog hyperbola kom zoo, peb yuav tsum nkag siab nws cov lus txhais geometric, daim ntawv txheem ntawm nws cov kab zauv, nws cov ntsiab lus sib xyaw, thiab yuav ua li cas cov kab zauv hyperbola tuaj yeem ua tau... nyeem ntxiv
Lub Txheej Txheem Tus Naj Npawb Binary Lub txheej txheem tus lej binary yog ib qho ntawm cov tswv yim tseem ceeb tshaj plaws hauv kev suav lej niaj hnub no. Yuav luag txhua lub cuab yeej digital uas peb siv txhua hnub - los ntawm xov tooj ntawm tes thiab khoos phis tawj mus rau ATMs thiab Internet of Things devices - ua cov ntaub ntawv hauv daim ntawv binary. Txawm hais tias lub kaw lus decimal (base 10) zoo li ntuj tshaj plaws rau tib neeg vim peb tau siv rau kev suav ... nyeem ntxiv
Cov Txheej Txheem Rov Ua Dua Rau Kev Nrhiav Cov Hauv Paus Hauv kev siv lej, physics, engineering, thiab computer science, qhov teeb meem ntawm "kev nrhiav hauv paus" tshwm sim ntau zaus. Ib qho hauv paus ntawm no yog tus nqi ntawm \(x\) uas ua rau muaj kev ua haujlwm xoom, uas yog, qhov kev daws teeb meem rau qhov sib npaug: \[ f(x)=0 \] Tsis yog txhua qhov sib npaug muaj cov kev daws teeb meem uas tuaj yeem qhia tawm hauv cov qauv kaw zoo li… nyeem ntxiv
Yuav Ua Li Cas Xam Qhov Cheeb Tsam ntawm Rhombus Ib daim duab rhombus yog ib daim duab dav hlau uas peb feem ntau ntsib hauv cov lus qhia lej, tshwj xeeb tshaj yog hauv geometry.
