Ob tug kab sib npaugyog tias lawv muaj qhov sib npaug. Cov kab y=2x + 1 thiab y=2x + 3 yog qhov sib npaug, vim tias ob qho tib si muaj gradient ntawm 2. Ob kab yog perpendicular yog tias ib qho nyob ntawm kaum sab xis mus rau lwm qhov - hauv lwm lo lus, yog tias ob kab hla thiab lub kaum sab xis ntawm cov kab yog 90 degrees.
Yuav ua li cas yog tias ob kab muaj tib qhov gradient?
Ib yam lus, nqes hav ntawm kab sib npaug sib npaug. Nco ntsoov tias ob kab yog qhov sib npaug yog tias lawv txoj kab nqes sib npaug thiab lawv muaj qhov sib txawv y-intercepts. Nyob rau hauv lwm yam lus, perpendicular slopes yog tsis zoo reciprocals ntawm ib leeg.
gradient zoo li cas?
Qhov no yog vim gradient thiab slope txhais tau tib yam. Qhov no nyob ntawm seb koj nyob qhov twg hauv lub ntiaj teb no. Gradient: (Mathematics) Qhov degree ntawm steepness ntawm daim duab ntawm txhua qhov chaw. Slope: Qhov gradient ntawm daim duab ntawm txhua qhov taw tes.
Txoj haujlwm sib txawv puas muaj qhov sib txawv?
Yog ob txoj haujlwm muaj qhov sib npaug, ces lawv yog qhov ua haujlwm tib yam.
txhais tau tias nrhiav qhov gradient?
Hauv kev ua lej, qhov gradient yog ntsuas qhov steepness ntawm txoj kab ncaj. Ib qho gradient tuaj yeem nce toj hauv kev taw qhia (los ntawm sab laug mus rau sab xis) lossis nqes toj hauv kev taw qhia (ntawm sab xis mus rau sab laug). Cov qhab nia tuaj yeem yog qhov zoo lossis qhov tsis zoo thiab tsis tas yuav yog tus lej tag nrho.
