• Vector Addition

  Jan 06, 2021 permanent    GameMath  LinearAlgebra

  

  We add two Vectors together by adding the corresponding components.

  $\vec{a}+\vec{b}=\left[\begin{array}{c}{a}_1\\ a_2\end{array}\right]+\left[\begin{array}{c}{b}_1\\ b_2\end{array}\right]=[\begin{array}{c}{a}_1+b_{\mathrm{1\; \dots }}\end{array}$

  We subtract one Vector from another by subtracting the corresponding components.

  $\vec{a}-\vec{b}=\left[\begin{array}{c}{a}_1\\ a_2\end{array}\right]-\left[\begin{array}{c}{b}_1\\ b_2\end{array}\right]=[\begin{array}{c}{a}_1-b_{\mathrm{1\; \dots }}\end{array}$
