WebGiven A x⃑ = b⃑ where A = [[1 0 0] [0 1 0] [0 0 1]] (the ℝ³ identity matrix) and x⃑ = [a b c], then you can picture the identity matrix as the basis vectors î, ĵ, and k̂.When you multiply out the matrix, you get b⃑ = aî+bĵ+ck̂.So [a b c] can be thought of as just a scalar multiple of î plus a scalar multiple of ĵ plus a scalar multiple of k̂. WebIn the earlier figure, there are twelve blue rays emanating from the origin and the angle between each pair of consecutive rays is 3 0 ∘ 30^{\circ} 3 0 ∘. The line segment A P 1 A P_1 A P 1 is perpendicular to ray L 1 L_1 L 1 , the line segment P 1 P 2 P_1 P_2 P 1 P 2 is perpendicular to ray L 2 L_2 L 2 , and so on.

WebAug 21, 2015 · Consider an orthonormal basis ${\{v_1,v_2\}}$ in the plane. Say any object (e.g. a vector, shape etc.) in the plane is defined with respect to this basis - so if we can rotate the basis vectors through the angle $\theta$ anticlockwise, this will transform any such defined objects in the same way.
