Dilations ua , txawm li cas los xij, khaws cia lub kaum sab xis. Ib daim duab thiab nws cov duab tom qab a dilation yuav zoo sib xws, txhais tau tias lawv yuav zoo tib yam tab sis tsis tas yuav tsum muaj qhov loj me.
Yog li ntawd, dab tsi dilations khaws cia?
Nws txhais tau tias dilations daim ntawv qhia cov kaum rau kaum, thiab cov dilation khaws cia qhov ntsuas ntawm cov kaum sab xis. dilations : 1. Dilations daim ntawv qhia kab rau kab, rays rau rays, thiab ntu mus rau ntu.
Ib yam li ntawd, yuav ua li cas thaum ib kab yog dilated? Thaum ib daim duab yog dilated , ib ntu (sab) ntawm cov duab ua ntej uas tsis dhau los ntawm qhov chaw ntawm dilation yuav parallel rau nws cov duab. Tswv yim 3: The dilation ntawm a kab ntu ntev dua lossis luv dua hauv qhov piv tau muab los ntawm qhov ntsuas qhov ntsuas.
Tsis tas li ntawd, dab tsi tseem tsis hloov pauv raws li kev dilation?
Lub chaw yog tib yam invariant (tsis hloov) taw tes nyob rau hauv ib tug dilation (k ≠1), thiab tej zaum yuav nyob rau sab hauv, sab nraud, lossis ntawm daim duab. Nco tseg: A dilation Tsis yog hu ua kev hloov pauv tsis tu ncua (lossis isometry) vim tias daim duab tsis tas yuav tsum tau tib yam loj raws li cov duab ua ntej (thiab kev hloov pauv tsis tu ncua khaws cia ntev).
Lub dilation cuam tshuam li cas lub kaum sab xis ntsuas?
Kev piav qhia: Dilation (scaling) yog lub hauv paus tseem ceeb rau qhov zoo sib xws hauv geometry. Nws transforms ib kab mus rau hauv ib tug parallel rau nws. Yog li ntawd, ib daim duab ntawm ib lub kaum sab xis scaled mus rau lwm qhov chaw yog lwm lub kaum sab xis nrog correspondingly parallel sab.

Koj pom txoj kab nqes ntawm txoj kab hauv AutoCAD li cas?
Txhawm rau tso saib qhov nqes hav nruab nrab ntawm ob lub ntsiab lus Nyem Tshawb tab Tshawb nrhiav vaj huam sib luag Sau nqe nqes. Nrhiav. Xaiv ib kab lossis ib qho arc, lossis sau p txhawm rau qhia cov ntsiab lus. Yog tias koj nkag mus rau p, qhia qhov chaw pib thiab qhov xaus rau kab. Cov txiaj ntsig ntawm kev suav yog tso tawm rau ntawm kab hais kom ua. Yog tias koj tsis pom kab hais kom ua, nias Ctrl + 9 los tso saib nws
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Vim li cas txoj kab kab rov tav muaj txoj kab nqes ntawm 0?
Mathwords: Zero Slope. Txoj kab nqes ntawm kab rov tav. Kab rov tav kab muaj nqes 0 vim tias tag nrho nws cov ntsiab lus muaj tib y-coordinate. Yog li ntawd, tus qauv siv rau txoj kab nqes ntsuas rau 0
Puas yog kab rov tav txoj kab nqes 0 lossis tsis tau txhais?
Ib yam li 'Z' (nrog nws ob kab kab rov tav) tsis zoo ib yam li 'N' (nrog nws ob txoj kab ntsug), yog li 'Xoom' txoj kab nqes (rau kab kab rov tav) tsis zoo ib yam li 'Tsis yog' txoj kab nqes (rau kab ntsug). Tus naj npawb 'zero' tshwm sim, yog li kab rov tav muaj tseeb muaj txoj kab nqes
Puas yog txoj kab ntsug yog txoj kab nqes?
Qhov 'slope' ntawm ib txoj kab ntsug. Ib txoj kab ntsug tsis tau txhais txoj kab nqes vim tias tag nrho cov ntsiab lus ntawm kab muaj tib x-coordinate. Raws li qhov tshwm sim, cov qauv siv rau txoj kab nqes muaj tus lej ntawm 0, uas ua rau txoj kab nqes tsis tau txhais
