Ma Vector Ofanana

M'bukuli, tiwona ma vector omwe amatchedwa ofanana komanso momwe angadziwire kuti ali ofanana. Tisanthulanso zitsanzo za ntchito pamutuwu.

Mkhalidwe wofanana wa ma vector

Ma Vector a и b ali ofanana ngati ali ndi zofanana , amagona pa mizere yofanana kapena yofanana, komanso kuloza mbali imodzi. Ndiko kuti, ma vector oterowo ndi ma collinear, amawongoleredwa komanso ofanana kutalika.

a = b, ngati a ↑↑ b ndi |a| | = |b|.

Zindikirani: ma vectors ndi ofanana ngati ma coordinates awo ali ofanana.

Zitsanzo za ntchito

Ntchito 1

Ndi ma vector ati omwe ali ofanana: a = {6; 8}, b = {-2; 5} и c = {6; 8}.

Kusankha:

Mwa ma vector omwe atchulidwa ndi ofanana a и c, popeza ali ndi zogwirizanitsa zomwezo:

a_x = c_x = 6

a_y = c_y = 8.

Ntchito 2

Tiyeni tione phindu lake n mavekitala a = {1; 18; 10} и b = {1; 3n; 10} ndi ofanana.

Kusankha:

Choyamba, yang'anani kufanana kwa ma coordinates odziwika:

a_x = b_x = 1

a_z = b_z = 10

Kuti kufanana kukhale koona, ndikofunikira kuti a_y = b_y:

3n = 18, choncho n = 6.
