The master came to support the move, and used it urgently!!

It should be that you have done something wrong, so that he is not at ease with you, thinking that going on like this will hurt her, find what you are not doing well enough, and try to correct it, now you may have broken her heart, you should talk to her first, be sincere, and remember not to provoke her.

The question is a bit vague, and the questions don't match each other! I also offended a class in pursuit of a girl, and I also robbed my girlfriend and her ex-boyfriend's class, and I almost got done, but I had the upper hand...

As for why I bother you, it has nothing to do with you robbing a woman, your own reasons.

Who told you to rob someone else's girlfriend?

The hero's final ending is all lonely drops...

You're doing it wrong....From the moment she snatched her......

Then you just hold on and know that you regret that day. Maybe that day will never come.

Ignore this woman and reconcile with your classmates.

Let z=z(x y) be a binary function determined by the equation cos x+cos y + cos z=1 and find z x

Solution: As a function f(x,y,z)=cos x+cos y+cos z-1=0, then:

To find the derivative of implicit functions, I suggest that you follow my approach: it is easier to find it with the derivative formula of implicit functions. 】

1 11, with Hardy's law, if AA is 1%, then the A gene accounts for 10% and A accounts for 90%, then the male AA is 81% and AA is 18%.

Boys with normal phenotypes are then (81 99) are AA and (18 99) are AA.

The probability of a child suffering from AA is (18 99) 2

Owe 49 to Dad, 49 to Mama, 49 49 = 98

Then I used 97 to buy shoes, plus 1 of my own, 97 + 1 = 98

98 (money owed) = 98 (money spent and money left) Neither less nor more.

Buying shoes totals 97 yuan divided by 2 + the remaining 3 yuan divided by 2 equals 50, and two people owe 50 each.
