2、1個(gè)。 7．， 8． 9．； 10． 11． 12．； 13．； 四．證明題 1．若函數(shù)f(z)在z0處可導(dǎo)，則f(z)在z0連續(xù)。 證明：直接利用定義。 2．若數(shù)列收斂，則與都收斂。 證明：利用不等式: 即可。 3．若整函數(shù)f(z)將復(fù)平面映照為單位圓內(nèi)部且，則。 證明：由于整函數(shù)f(z)將復(fù)平面映照為單位圓內(nèi)部且，則整函數(shù)f(z)是一個(gè)有界整函數(shù)，由劉維爾定理知道，。 4．證明方程在內(nèi)僅有3個(gè)根。 證明：在上，由得，在單位圓內(nèi)只有一個(gè)根，在利用在上，由得，在有4個(gè)根，所以方程在內(nèi)僅有3個(gè)根。 "If we dont do that it wi

3、ll 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 Ivory Coast international Toure to discuss his complaint. CSKA general director Roman Babaev says

4、 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 can always find money from somebody to pay them. "It is a nonsense to have matches played without

5、 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 we have today in our game. But it is only with harsh sanctions that racism and discrimination can

6、 be washed out of football." The (lack of) air up there Watch mCayman Islands-based Webb, the head of Fifas anti-racism taskforce, is in London for the Football Associations 150th anniversary celebrations and will attend Citys Premier League match at Chelsea on Sunday. "I am going to be at

7、 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." Uefa hasopened disciplinary proceedings against CSKAfor the "racist behaviour of their fans" duringCitys 2-1 win.

8、 Michel Platini, president of European footballs governing body, has also ordered an immediate investigation into the referees actions. CSKA said they were "surprised and disappointed" by Toures complaint. In a statement the Russian side added: "We found no racist insults from fans of CSKA." Baumg

9、artner 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 very calm -- winds less than 2 mph, with no precipitation or humidity and limited cloud cover. T

10、he 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/8.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 mi

11、les/9.17 kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. The balloon will slowly drift to the edge of space at 120,000 feet ( Then, I would assume, he will slowly step out onto something resembling an Olym

12、pic diving platform. Below, the Earth becomes the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, hell be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the shallow end. Skydiv

13、er 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 approaches the more dense air closer to Earth. But this will not be enough to stop him completely.

14、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-square-meter) main chute at an altitude of around 5,000 feet (1,524 meters). In order to deploy thi

15、s 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). cause there 第 4 頁 共 4 頁
