I found an easy-to-understand definition of accredited homeschooling on Wikipedia: Accreditation is a type of quality assurance process under which a facility's or institution's services and operations are examined by a third-party accrediting agency to determine if applicable standards are met.
Sections: Introduction, Finding information from the equation, Finding the equation from information, Word Problems. An ellipse, informally, is an oval or a squished circle. In primitive geometrical terms, an ellipse is the figure you can draw in the sand by the following process: Push two sticks into the sand. Take a piece of string and form a loop that is big enough to go around the two sticks and still have some slack.
Unfortunately, ellipses fail to satisfy many of the invariants of circles; if Circle has a method radius, Ellipse will now have to provide it as well. The problem is sometimes expressed in statements such as a Circle is not a sort of Ellipse . This looks confusingly like the absurd a circle is not a sort of ellipse, and sounds identical, so it is unhelpful. What is actually meant is an OO-model of a circle should not be a sort of OO-model of an ellipse.
