tirotiro
I roto i tenei whakaputanga, ka whakaaro tatou me pehea te whakarea o te vector ki te tau (te whakamaori ahuahanga me te tauira taurangi). Ka whakarārangihia hoki e mātou ngā āhuatanga o tēnei mahi me te tātari i ngā tauira mahi.
Te whakamaoritanga ahuahanga o te mahi
Mena ko te vector a whakareatia ki te tau m, ka whiwhi koe i te vector b, kei roto:
- b || a
- |b| = |m| · |a|
- b ↑↑ a, ki te m > 0,
b ↑ ↓ aki te m <0
No reira, ko te hua o te vector kore-kore ma te tau he vector:
- collinear ki te taketake;
- te aronga tahi (mehemea he nui ake te tau i te kore) he huarahi rereke ranei (mehemea he iti iho te tau i te kore);
- He rite te roa ki te roa o te vector tāuru kua whakareatia ki te kōwae o te tau.
Ko te tātai hei whakarea i te vector ki te tau
Te hua o te vector kore-kore ma te tau he vector e rite ana ona taunga ki nga taunga o te vector taketake, ka whakareatia ki tetahi tau.
