Completing the square was a method that was discovered in order to solve quadratic equations. This method was discovered by Muhammad ibn Musa al-Khwarizmi, a Persian mathematician, astronomer, and geographer. Al-Khwarizmi, also known as the father of Algebra, wrote “The Compendious Book on Cal...
The fourth method of solving a quadratic equation is by using the quadratic formula, a formula that will solve all quadratic equations. Although the quadratic formula works on any quadratic equation in standard form, it is easy to make errors in substituting the values into the for...
Also, the method of completing the square can be used to derive the quadratic formula, should you ever forget it — and it's easy to forget a formula that you simply learned by heart and never fully understood. Finally, if you ever face integration problems, you'll be thankful you've ...

This note proposes a new method to complete a triangulated category, which is based on the notion of a Cauchy sequence. We apply this to categories of perf
It is important to think about where the drawing sheets will be located. One approach is to create a single file containing all the drawings for the project. This file would contain no model elements at all, just sheets and annotations. However, this method meant the drawing file would have...
