Vector addition combines vectors head-to-tail; results in resultant vector (parallelogram method or component-wise).
Trinn-for-trinn guide
- 1Input two vectors (component form)
- 2Add components: (a₁+b₁, a₂+b₂, a₃+b₃)
- 3Results show sum vector and magnitude
Løste eksempler
Inndata
a=(3,4), b=(1,2)
Resultat
a+b=(4,6), |a+b|=√52≈7.21
Vanlige feil å unngå
- ✕Adding magnitudes instead of components
- ✕Confusing with scalar multiplication
Ofte stilte spørsmål
Is vector addition commutative?
Yes, a+b = b+a (unlike subtraction).
