Vektorka Halbeegga ee Vektorka
Vektarrada waa fikrad aasaasi ah oo ku saabsan xisaabta iyo fiisigiska, oo inta badan loo isticmaalo in lagu qeexo ifafaale dabiici ah oo kala duwan sida dhaqdhaqaaqa, xoogga, iyo xawaaraha. Vektarrada waxay leeyihiin baaxad iyo jihayn, laba astaamood oo ka soocaya scalars, kuwaas oo leh baaxad iyo jiho keliya. Noocyada kala duwan ee vektarrada, vektarrada cutubyadu waxay ciyaaraan door gaar ah oo muhiim ah. Maqaalkani wuxuu si qoto dheer u sharxi doonaa waxa vektarrada cutubyadu yihiin, sida loo xisaabiyo, iyo adeegsigooda qaybaha kala duwan.
Waa maxay Vektor-ka Cutubka?
Vektor cutub waa vektor leh dherer ama baaxad hal cutub ah. Ujeeddada ugu weyn ee loo isticmaalo vektor cutub waa in la go'aamiyo jihada vektor iyada oo aan la tixgelin baaxaddiisa. Vektorrada cutubyadu aad bay waxtar ugu leeyihiin codsiyada farsamo iyo kuwa cilmiyeed ee kala duwan, maadaama ay fududeeyaan falanqaynta iyo xisaabinta la xiriirta jihada.
Calaamadaynta Vektor-ka Cutubka iyo Calaamadaha
Guud ahaan, qoraalka vektor-ka cutubka waxaa badanaa loo qoraa xaraf yar oo leh koofiyad (^) korkiisa. Tusaale ahaan, haddii aan leenahay vektor \( \mathbf{v} \), markaa vektor-kiisa cutubka waxaa loo qoraa sida \( \hat{\mathbf{v}} \). Saddex cabbir, vektor-yada cutubka ee ku teedsan x-, y-, iyo z-axes waxaa badanaa loo tilmaamaa \( \hat{i} \), \( \hat{j} \), iyo \( \hat{k} \) siday u kala horreeyaan.
Xisaabinta Vektorrada Cutubka
Si loo xisaabiyo vektor-ka cutubka \( \hat{\mathbf{v}} \) ee vektor \( \mathbf{v} \), waa inaan vektor-ka u qaybinnaa dhererkiisa ama baaxaddiisa. Xisaab ahaan, tan waxaa loo qori karaa sidan:
\[ \hat{\mathbf{v}} = \frac{\mathbf{v}}{|\mathbf{v}|} \]
Halkee \( |\mathbf{v}| \) uu yahay dhererka ama baaxadda vektorka \( \mathbf{v} \).
Tallaabooyinka lagu Xisaabinayo Vektorrada Cutubyada
1. Go'aami baaxadda vektorka \( \mathbf{v} \):
Wixii vektor \( \mathbf{v} = \langle v_1, v_2, v_3 \rangle \), cabbirka waxaa lagu xisaabin karaa qaacidada:
\[ |\mathbf{v}| = \sqrt{v_1^2 + v_2^2 + v_3^2} \]
2. Qayb kasta oo Vektor ah u qaybi Balanqaadka:
Ka dib markaan helno baaxadda, waxaan qayb kasta u qaybinaynaa \( v_1, v_2, v_3 \) iyadoo loo marayo \( |\mathbf{v}| \) si aan u helno qaybaha vector-ka cutubka \( \hat{\mathbf{v}} \):
\[ \hat{\mathbf{v}} = \left\langle \frac{v_1}{|\mathbf{v}|}, \frac{v_2}{|\mathbf{v}|}, \frac{v_3}{|\mathbf{v}|} \right\rangle \]
Tusaale Xisaabinta Vektor-ka Cutubka
Ka soo qaad inaan haysanno vektor \( \mathbf{v} = \langle 3, 4, 0 \rangle \). Aan xisaabino vektor-keeda cutubka.
1. Go'aami baaxadda vektorka \( \mathbf{v} \):
\[ |\mathbf{v}| = \sqrt{3^2 + 4^2 + 0^2} = \sqrt{9 + 16 + 0} = \sqrt{25} = 5 \]
2. Qayb kasta oo Vektor ah u qaybi Balanqaadka:
\[ \hat{\mathbf{v}} = \left\langle \frac{3}{5}, \frac{4}{5}, \frac{0}{5} \right\rangle = \left\langle \frac{3}{5}, \frac{4}{5}, 0 \right\rangle \]
Markaa halbeegga vector-ka \( \hat{\mathbf{v}} \) ee \( \mathbf{v} = \langle 3, 4, 0 \rangle \) waa \( \hat{\mathbf{v}} = \langle 0.6, 0.8, 0 \rangle \).

Vektor kasta oo ku jira meel saddex-cabbir ah waxaa lagu tilmaami karaa isku-darka toosan ee vektorrada cutubyadan. Tusaale ahaan, vektor \( \mathbf{v} = \langle v_1, v_2, v_3 \rangle \) waxaa loo qori karaa sidan:
\[ \mathbf{v} = v_1 \hat{i} + v_2 \hat{j} + v_3 \hat{k} \]
