Astronomers use them to determine the paths of planets, someone in medicine might recommend a patient get a lithotripsy (a procedure which utilizes the reflective properties of ellipses) to remove a kidney stone, opticians use them for the manipulation of light (for example the making of a microscope), and aerospace engineers use them for space stuff.
Most orbits are ellipses.
The ellipses were discovered in the 17th century by one Johannes Kepler. Johannes Kepler discovered that the orbits along which the planets travel around the Sun are ellipses with the Sun at one focus, in his first law of planetary motion.
The correct way to use ellipses is to indicate when something has been left out. They are mostly used when quoting something. For example: The question asked, "How do you use...correctly?"You will use ellipses mostly when using other people's writing to back up your own argument. If you want to quote a sentence, but you only like the first part and the last part, not the middle, then you can use ellipses to indicate that you have not quoted the middle part.
Ellipses
to show that something is missing.

Ellipses are a scientific word for the shape of an oval. for example the planets orbits are ellipses.
Ellipses show that a portion of the quote has been left out, which might mean that it was irrelevant to the purpose of the quote, but which could change the meaning of the quote if taken out of context.
To show that something is missing
Ellipses are not circles.
There are many careers that use variables and equations regularly. Computer scientists, engineers, and scientists all depend on the use of variables and equations. Architects, plumbers, and home decorators also utilize variables and equations.
Oh, dude, there are plenty of careers that use the mathematical formula for volume. Like architects use it to design buildings, chefs use it to measure ingredients, and even divers use it to calculate how much air they need in their tanks. So, yeah, knowing your volume formula can come in handy in more ways than you'd think.
