In the high school mathematics knowledge ellipse, the ellipse is the locus of the moving point P whose sum of the distances between each fixed point F 1 and F2 on the plane is equal to a constant (greater than |F 1F2|), and F 1 and F2 are called the two focuses of the ellipse. The mathematical expression is | pf1|+pf2 | = 2a (2a > | f1F2 |). Let's take a look at the ellipse of high school mathematics knowledge points.

Drawing method of 1 ellipse

2. Axis endpoint: an axis with two endpoints and another endpoint.

3. The drawing method of elliptical arc: it has a starting angle and an ending angle. Select an elliptical arc to determine the endpoint of the axis.

Geometric properties of 1 ellipse

The related formula of 1 ellipse

In the knowledge points of high school mathematics, the ellipse is often a combination of numbers and shapes. It brings the combination of number and shape into computational mathematics and uses formulas to calculate. The above are the knowledge points of high school mathematics that I summarized for you: ellipse drawing and its related knowledge, hoping to help students who study high school mathematics. c _ Kan()；
