Rotation
Main Concept
A point is rotated by an angle θ, if the original point, center of rotation and the new point make an angle of exactly θ. Similar to a reflection, a graph can be rotated by an angle θ if each point in the graph is rotated in the same direction by θ.
Choose a function and an angle of rotation and click on the Rotate Graph button to rotate it. Click on the plot to change the center of rotation (blue). Note that the function will rotate counter-clockwise around the center of rotation.
Function: cos(x)tan(x)x^2exp(x)
Rotation angle (degrees):
