Solve the cards!! Details Thank you 5

My low hand, you want to solve the card in detail I will solve the process of the card to you to write out, I will not be in series, I hope it will be useful to you, the meaning of the cards is generally the same, in fact, you already know the answer, just want to say it through other people's mouths.

The wheel of fortune represents a new starting point, a new beginning Here it means that for you, this election is a very good opportunity, you are very surprised and surprised to participate in this election, the reversed hermit said that the details start to communicate with people more, believe in yourself, be a high-profile person and do things in a low-key manner, the female pope of the reversal I don't know if you are a man or a woman, indicating that you must have a high degree of understanding and judgment and affinity in the election process.

Temperance and rebellion do not attack your opponent to maintain generosity, to have a good and healthy psychological state, the final result of the devil is no result, your so-called good or bad results all lie in whether you work hard, in fact, you lack confidence in yourself, the election results are not optimistic, what is the point of calculating a good card, ask your heart more, but ask yourself, think about what you want in your heart! ~

I'm struggling to type word by word, so it's not easy to give more points! ~~

Such a tough question, you only give 5 points, it's a bit picky, this question needs to be renewed by a master to ......See how ...... you performed

According to the kinetic energy theorem, there is wf-wf δek, so wf wf δek f s mv 2

Velocity v p f at the time of the last uniform motion

Substituting the above equation can find wf

When x approaches 0, the price of 1-cos2x is higher than that of x2, so 1-cos3x is equivalent to one-half of 3x by changing the square of Zheng Zhen of 2 and replacing sinx with x.

The original formula can be written as 1 x -1 (1+x), and then solved to get -1 x +arctanx

Parse. dy/dx

It's the derivative. So.

dy/dx=2x

At this time y'=2x

So C right. Hope it helps.

Learning progress o ( o thank you.

2x,dy is better than dx is to do a guide to y ah get 2x,sweat you didn't study hard in high math.,Or is this a high school problem?

2x+x 2+9y 2+2=-6y, (note: x 2=x squared) all moved to the left of the posture, and according to the decreasing power of each letter, divide 2 into 1+1x 2+2x+1)+(9y 2+6y+1)=0x+1) 2+(3y+1) 2=0

Therefore, x=-1, y=-1 3 are substituted into the desired formula, and they get.

x-3y=-1-3(-1/3)=0

2mol is greater than.

Also subtract the amount of oxygen produced.
