Vector addition

The resultant of adding two vectors together, say V₁ at an angle θ₁ and V₂ at angle (–θ₂), as shown in Figure 71.1(a), can be obtained by drawing oa to represent V₁ and then drawing ar to represent V₂ . The resultant of V₁ + V₂ is given by or. This is shown in Figure 71.1(b), the vector equation being oa oa + ar = or https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429294402/968186b9-ffa4-4f2b-aa54-7fc58a604561/content/eq2466.tif"/> . This is called the ‘nose-to-tail’ method of vector addition.
