WebIf the angle is positive, the terminal side rotates counter clockwise, and if the angle is negative, the terminal side rotates clockwise. For example, if the terminal side was on the the positive y-axis (above the origin), then the angle made would be 90 degrees, because the terminal side rotated 90 degrees counter clockwise. Hope this helps! WebAug 21, 2015 · Firstly, note that the operation of rotation through θ about origin O (let us call this operation T) is a linear transformation i.e. T ( v → + w →) = T ( v →) + T ( w →) and T ( α v →) = α T ( v →) for v →, w → ∈ R 2, α ∈ R. So we have linear T: R 2 → R 2. top 25 ncaa football rankings
