I m so depressed, I hope the master suggests!

In today's society, there is no culture, no craftsmanship. Then don't expect a bright future.

To find your hobby and pursue your dreams is the first step A machine cannot function without power.

In today's society, some of them are very realistic, they have no education, they don't have skills, and it's hard to find easy jobs with good income.

Once you've found what you're looking for, it's time to recharge your batteries.

Nowadays there are many training schools and centers of all kinds.

The line is the champion.

I don't know what your dreams will be.

But you know, success also involves luck.

By the way, give a piece of advice, what kind of industry you are in, and communicate with people first, remember not to give up just thinking about giving up.

One thought can often be reflected in the mind, and it can be catalyzed by something to become the next thing, and everything has to be optimistic.

Make more friends, work is like this, even if you change the working hours for a long time in the future, it will still be like this, find fun at work, and have the gas to talk to friends.

No one wants to work. Because there are always things that can't be done at work, and there is anger that can't be endured. The best way to overcome it is to find a partner of the opposite sex, a match between men and women, and work without getting tired.

In order to show your best side, no matter how bitter it is, you are willing to do it. A little advice, I hope you are happy!

Solution: (1) When a=1, f(x)=2lnx-x2, f(x)=2x, f(1)=0 ....

and f(1)=-1, the tangent equation for the curve y=f(x) at x=1 is y+1=0 ....

3）∵f（x）=2a2lnx-x2，∴f′（x）=

x 0, a 0, f (x) 0 when 0 x a, f (x) 0 when x a

f(x) is an increasing function on (0,a] and a subtracting function on [a,+....

f（x）max=f（a）=a2（2lna-1），…

The zero point case of the function f(x) is discussed as follows

a2(2lna-1) 0, i.e., at 0 a, the function f(x) has no zero point, and there is no zero point on (1,e2); ...

When a2(2lna-1)=0, i.e., a=, the function f(x) has a unique zero point a in (0,+), and 1 a e2, f(x) has a zero point in (1,e2); ...

When a2(2lna-1) 0, i.e., a, since f(1)=-1 0, f(a)=a2(2lna-1) 0 f(e2)=(2a-e2)(2a+e2), when 2a-e2 0, i.e., 1 e2,f(e2) 0, it can be seen from the monotonicity that the function f(x) has a unique zero x1 in (1,a), a unique zero x2 in (a,e2) satisfies, and f(x) has two zeros in (1,e2); …

When 2a-e2 0, i.e., f(e2) 0, and 0, f(1)=-1 0, it can be seen from monotonicity, whether a e2 or a e2, f(x) has a unique zero point in (1, ), and there is no zero point in [ , e2), so that f(x) has only one zero point in (1,e2); ...

In summary, there are: when 0 a, the function f(x) has no zero point; When a= or , the function f(x) has a zero point; When , the function f(x) has two zeros.

Because AD Ping guesses the honor line EF, angle one is equal to angle two.

Because angle one is equal to angle two, gd is parallel ab

It should be gd parallel to the mega ab so the angle gdc is equal to the laughing trillion angle b

Ad EF Sakura stupid with horn 3 + horn sensitive potato EFA is 180

So angle 1 is equal to angle 3

So the bridge singer da ef so the angle 8 is equal to the angle cdg

It is known that ab=de, bc=ef, and b=anglee meet the two sides of the horn of the field.

So the triangle abc and the triangle are definitively congruent.

So angular ACB = angular DFE

And because the angle ACB + angle volt premature elimination ACF = 180, the angle DFE + angle DFC = 180, so the angle ACF = angle DFC

So AC is parallel to DF (the inner misalignment angle is equal).
