  • If  \(\overrightarrow {OP}\) =  \(\begin{pmatrix}x\\y\\\end{pmatrix}\) then the magnitude of \(\overrightarrow {OP}\) i.e |\(\overrightarrow {OP}\)| = \(\sqrt{x^2+y^2}\) and Direction : tan\(\theta\) = \(\frac{y}{x}\)
    • _x000D_
  • If A(x1,y1) and B (x2,y2) then column vector ( \(\overrightarrow {AB}\)) =  \(\begin{pmatrix}x_2-x_1\\y_2-y_1\\\end{pmatrix}\)
    • _x000D_
