These terrorist and commingled remains were turned over to the Federal Bureau of Investigation (FBI) in February 2002. The FBI said the remains were "disposed of in a dignified manner'", although a very small amount of suspected terrorist remains were retained to aid in later criminal prosecutions. The Victims of Terrorist Attack on the Pentagon Memorial was dedicated on September 12, 2002. A funeral service for the 30 victims was held at the Arlington Memorial Amphitheater, the first time the amphitheater had held such
Heptagon polynomial is the minimal polynomial of 2cos(), whereas the degree of the minimal polynomial for a constructible number must be a power of 2. An approximation for practical use with an error of about 0.2% is shown in the drawing. It is attributed to Albrecht Dürer. Let "A" lie on the circumference of the circumcircle. Draw arc "BOC". Then formula_8 gives an approximation for the edge of the heptagon. This approximation uses formula_9 for the side of the heptagon inscribed in the unit circle while the exact value is formula_10. "Example to illustrate the error: At a circumscribed circle radius
