Print our sixth grade (grade 6) worksheets and activities or administer as online tests. Share. Rotation in mathematics is a concept originating in geometry.Any rotation is a motion of a certain space that preserves at least one point.It can describe, for example, the motion of a rigid body around a fixed point. Back to Math and Physics. That makes the coordinates ( x, y) of the point where the other side of the angle intersects the circle so that x = cos and y = sin . That's consistent with Euler's identity in the complex plane: e i = cos + i sin . One side of an angle is placed on the positive x-axes, the angle is measured counterclockwise.
