James A. Garfield, the twentieth president of the United States, discovered an original proof of the Pythagorean theorem. The proof is algebraic in nature and uses the formula for the area of a trapezoid. See the link below for details. Garfield is credited with an original proof of this famous theorem. Many of the presidents undoubtedly proved it in geometry class after studying their books.
Almost none of the new Generals had any training at high levels. Many were Colonels left over from the Mexican War, fifteen years earlier - a dubious qualification, as the Confederates found when they made Jefferson Davis President. The challenge was to choose and use largely untrained officers. Lincoln proved better than Davis at this.
Four U. S. Presidents have been assassinated. Five were shot, and at least one other was shot at without being hit, but it proved fatal for Abraham Lincoln in 1865, James A. Garfield in 1881, William McKinley in 1901 and John F. Kennedy in 1963.
For most of the war, there was no General-in-Chief of the Confederate armies. The President, Jefferson Davis, saw himself in that role, but proved to be a bad chooser and user of Generals. Eventually he appointed Robert E. Lee (the obvious choice) to that post, but it was too late to make any difference.
It proved he had excellent leadership qualities.
He was President of the Confederate States of America. He did not want the job - he was hoping to be made General-in-Chief of the Confederate armies. So he did not appoint anyone else to that job (until the last weeks of the war), and tried to do it himself. He proved unequal to the task - not able to control either his Generals or his cabinet.
January 20th 2009 Barack Obam will be sworn in unless it is proved he is not eligible to be President of the United States based upon the fact that he was born in Kenya and not in the United States nor is he a natural born citizen because his mother was not the legal age for him to automatically be natural born.
Team work is proved always helpful whether you are doing it in any field..So whether it is your business or any thing you should try and do the work in a team..It is always proved fruitful....
weak-willed & tolerant of corruption among his friends
The sniper who shot President Kennedy was proved to have been at the grassy knoll.
