You really don't have a show, she has a tendon now, she won't think you're right what you say, now that you're doing everything wrong, you can ignore her for the time being, if she can think of your good and come back naturally, otherwise it's over.

If she still wants to continue the relationship with you, you have to calm down and have a good chat, know each other's thoughts, know what each other can accept, and enhance each other's trust, so that you can manage this relationship well.

It is not excluded that if she wants to end the relationship in this way, so if she wants to manage her love well, she must communicate, trust, and know the other party's intentions.

You treat her well, she still has an opinion?? Then don't be nice to her.

The area of that quarter circle + the area of a quarter circle = the area of the square + the area of the shaded part.

The area of a quarter circle is: 2 2 4=

The area of the square: 2 2=2

Therefore, the area of the shaded part is: 2 -4

Equal, 1 and 3 90°, and 3 2 90° and 3 are common angles.

Thanks, yes, I promise it's correct.

It's equal. Because both rectangles are right angles. So angle 1 plus angle 3 is 90 degrees, and angle 2 plus angle 3 is also 90 degrees. So angle 1 and angle 2 are equal.

Dad + Mom + Xiaoqian = 80

Its cavity is in the old block: Xiaoqian = dad 4, mom = dad -1 gets: dad + (dad -1) + (dad with chop 4) = 80 can be found: dad = 36 years old.

That is, Ma Wu Hu Ma = 35 years old, Xiao Qian = 9 years old.

(1) Vector oa (1, sinx 1), vector ob (sinx sinxcosx, sinx), f(x).

Vector OA Vector OB Sinx Sinxcosx (Sinx 1) Sinx Sinxcosx (Sinx) 2

1/2）（sin2x＋1－cos2x）＝1/2＋（√2/2）［sin2xcos（π/4）－cos2xsin（π/4）］

1/2＋（√2/2）sin（2x－π/4）。

The maximum value of f(x) is (1 2) 2.

2) Obviously, when 2k 2 x 4 2k 2, f(x) is monotonically incrementing.

From 2k 2 x 4 2k 2k2, get 2k 4 2x 2k 3 4, k 8 x k 3 8.

The incrementing interval of f(x) is (k 8, k 3 8), where k is an arbitrary integer.
