2.證:設(shè)由圓周圍成的區(qū)域?yàn)?,易知,為有界閉區(qū)域.
因函數(shù)在內(nèi)不是常數(shù),在內(nèi)解析,且在有界閉區(qū)域上連續(xù),所以,由最大模原理有
這表明在內(nèi)取不到最大值,故它只能在的邊界上取到最大值,即在圓周上必存在一點(diǎn),使得,且有

"If we dont do that it will go on and go on. We have to stop it; we need the courage to do it."
His comments came hours after Fifa vice-president Jeffrey Webb - also in London for the FAs celebrations - said he wanted to meet Iv

CSKA general director Roman Babaev says the matter has been "exaggerated" by the Ivorian and the British media.
Blatter, 77, said: "It has been decided by the Fifa congress that it is a nonsense for racism to be dealt with with fines. You ca

"It is a nonsense to have matches played without spectators because it is against the spirit of football and against the visiting team. It is all nonsense.
"We can do something better to fight racism and discrimination.
"This is one of the villains w

"I am going to be at the match tomorrow and I have asked to meet Yaya Toure," he told BBC Sport.
"For me its about how he felt and I would like to speak to him first to find out what his experience was."

Michel Platini, president of European footballs governing body, has also ordered an immediate investigation into the referees actions.

Baumgartner the disappointing news: Mission aborted.
The supersonic descent could happen as early as Sunda.
The weather plays an important role in this mission. Starting at the ground, conditions have to be
12、very calm -- winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our day-to-day weather lives. It will climb higher than the tip of Mount Everest (5.5 miles/8
13、.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 miles/9.17 kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence.

Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform.

Skydiver preps for the big jump
When he jumps, he is expected to reach the speed of sound -- 690 mph (1,110 kph) -- in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he appr

If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes its not needed. Instead, he plans to deploy his 270-square-foot (25-squa
17、re-meter) main chute at an altitude of around 5,000 feet (1,524 meters).
In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds.
Even if everything goes as planned, it wont. Baumgartner still will free fall at a speed that would cause you and me to pass out, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters).
