👉 In mathematics, a revolution is a geometric transformation that involves rotating an object around a specified axis. It can be thought of as a rotation applied to one or more axes simultaneously. For example, if we rotate a point P around the x-axis (x=0) by 90 degrees clockwise, the result would be P' = (-y, 0). This means that P is at the origin (0, 0), rotated 90 degrees counterclockwise about the x
