Course Introduction:Speaking of CorelDrawX4 software, I believe that all the users here are familiar with it, but do you know how to make a parabola with CorelDrawX4? The following article brings you the method of making a parabola with CorelDrawX4. Let's go and learn together. We need to click on the fifth tool from the top first. Then we select "3 point curve" in the command below. Then we use the left mouse button and hold it still to draw a straight line. At this time we click to release and draw the third point. Draw it like in the picture. In the last step, the parabola is drawn.

Course Introduction:Draw line segment AB, and draw the perpendicular l of line segment AB through point A. Pick any point M on l, and draw a parallel line j to AB through M. Connect MB and draw the mid-perpendicular of line segment MB, which intersects at point N. Select points N and M in turn and execute the [Construction] - [Trajectory] command, thus constructing the trajectory of the point with point M as the driving point of N, and the parabola is drawn. Build tools. Select points A, B and the parabolic trajectory, click the custom tool button, select [Create New Tool], and name it [Parabolic Tool]. The parabolic tool is now created.

Course Introduction:1. Create a new geometric sketchpad file. Select the [Draw]-[Grid Style]-[Square Grid] command to draw a coordinate system. 2. Select the [Data]-[New Function] command, enter the equation as shown in the figure below, and click [OK]. 3. Select the upper left corner of the drawing board to generate the formula, select [Draw]-[Draw New Function] command to generate a parabola, 4. Keep the parabola selected, select [Construct]-[Point on Function Image] command, in this Pick any point A on the parabola. Select this point, select the [Measure]-[Abscissa] command to measure the abscissa value of point A. In the same way, measure the ordinate of this point. 5. Select the parabolic equation, then select the [Data]-[Define Derivative Function] command, and the first-order derivative function f will appear.

Course Introduction:In modern front-end development, using animation to improve user experience has become a part that cannot be ignored. Parabolic animation is one of them, which can bring a fun and relaxed feeling to the page and can be used in various scenarios that require user operations, such as adding items to a shopping cart. In this article, we will learn how to use Vue to implement a page design with parabolic animation. First, we need to understand what the nature of parabolic animation is. It mainly involves two key points: animation curves and animation parameters. An animation curve refers to a curved road
