I need help with example 5.4L. I can understand all the working steps but i don't understand how they get m1 and m2, which is the point of intersection of the two perpendicular tangent... Can anyone enlighten me?
The purpose of this example is to help you understand how to calculate the properties of an ellipse, specifically the values for m1 and m2.
An ellipse is a geometric shape that resembles a flattened circle. It has two focal points and all points on the ellipse are equidistant from these focal points.
m1 and m2 are the distances from the center of the ellipse to its two focal points. These values are used in the equation for calculating the properties of the ellipse.
To calculate m1 and m2, you need to know the length of the major axis (a) and the length of the minor axis (b) of the ellipse. Then, you can use the formula m1 = √(a² - b²) and m2 = -√(a² - b²).
Ellipses can be found in many natural and man-made structures, such as planetary orbits, the shape of an egg, or the design of a satellite dish. They can also be seen in the shape of some fruits, such as apples and watermelons.
