Detailed method of rotating function image using Geometric Sketchpad

Encountering difficulties when rotating function images in Geometry Sketchpad? PHP editor Apple brings you a detailed guide. Rotating function graphs involves a series of steps that require accurate input of parameters and mastery of software capabilities. This article will guide you through the rotation process step by step, making it easy for you to achieve the desired effect.

1. Create function image. [Drawing] - [New Function], enter [x], [^], [2] to draw the graph of the quadratic function.

2. Draw a circle and points on the circle. Use the [Circle Tool] to draw a circle with the origin as the center, and use the [Point Tool] to draw a free point P on the circle; the intersection point G of the circle and the y-axis.

3. Mark the rotation angle. Select points G, O, and P, and go to the menu [Transform] - [Mark Angle]. Use the [Point Tool] to construct a point A on the function graph.

4. Rotate point A. Double-click point O to mark the center, select point A, [Transform] - [Rotate], mark the angle rotation, and get point A’.

5. Construct the trajectory. Select points A and A’, [Construction] - [Trajectory]. Move point P, and the image trajectory will rotate accordingly.

Tips: Mark the angle as radians or modify the unit of the angle in [Edit] - [Parameter Options] to [Direction Degrees] or [Radians], the image can be in 360° Rotate within the range.
