How to prove it! 35, how to prove it!

Yes, you do love her.

Don't you think she's completely playing with you right now?

Do you balance your efforts when you're together?

You are in love, not looking for a Guanyin Bodhisattva to offer!

Excuse it, if she's going to break up with you and don't love you anymore, even if you prove it.

It's just an excuse, it's useless for you to do anything, don't deceive yourself and bring humiliation on yourself.

Nothing is absolute.

Feelings are no exception.

Time is the best way to prove things.

Is love able to stand its test.

It's actually about how deep each other's emotions are.

Acknowledging that time dilutes a lot of things.

But that doesn't mean it can make everything go away.

Sometimes don't trust time.

Don't blindly test love with time.

If you use time to test your love.

The result is regret.

Time can only play a supporting role.

Don't let it be the protagonist of your life.

Everything is in your own hands.

Wishing you happiness!

Speechless, she just can't say very heavy words to make you break up with her So, forget it and change it.

Don't hang yourself from a tree.

Listen to this song to her when you remember:

You are my heart, you are my liver".

When she is sad, comfort her; She is happy, and so are you; to meet her reasonable requests; Sweet words cannot be said too much, nor can they be said less; When she was sick, I felt sorry for her; When she is lonely, accompany her; When she is bullied, protect her; On her birthday, wish her.

If she really broke up with you, she wouldn't say this, since she asked for it, it means that she is not very willing, you just say more good things, behave very sincerely, and then seem to know what to do with her request, and she is anxious to die, she may think you are cute!

Very simple! Tell us about your life! What would happen if she didn't!

Proving the limit with a definition is a way to write a format, and drawing a gourd in the same way is.

It is proved that since the function f is continuous at the point x0, by definition, for any given >0( <1), there exists δ 0 such that when |x-x0|"When there is.

f(x)-f(x0)|

At this point, ||f(x)|-f(x0)||f(x)-f(x0)|

In addition, due to.

f(x)| f(x)-f(x0)|+f(x0)| 1+|f(x0)|, thus |f²(x)-f²(x0)| = |f(x)+f(x0)||f(x)-f(x0)|

|f(x)|+f(x0)|]f(x)-f(x0)|

1+2|f(x0)|]f(x)-f(x0)|

1+2|f(x0)|] by definitionf|, f is also continuous at x0.

The opposite is not true, eg.

f(x) = -1，x<0；

1， x≥0，……

Piano's axioms.

Piano's axioms, also known as Piano's axioms, are a system of five axioms about natural numbers proposed by the mathematician Piano (Piarot). According to these five axioms, a first-order arithmetic system, also known as the Piano arithmetic system, can be established. These five axioms of Piano are described in a non-formal way as follows:

1 is a natural number; For every definite natural number a, there is a definite successor a' ，a'It is also a natural number (the successor of a number is the number immediately following this number, e.g., the successor of 1 is 2, the successor of 2 is 3, and so on); If b and c are both successors of the natural number a, then b=c; 1 is not a successor to any natural number; Any proposition about a natural number can be proved to be true to n if it is proved to be true to the natural number 1 and assumed to be true for the natural number n'It is also true, then, that the proposition is true for all natural numbers. (This axiom is also called the inductive postulate, which ensures the correctness of mathematical induction) Note: The inductive postulate can be used to prove that 1 is the only natural number that is not a successor, because if the proposition is "n=1 or n is the successor of other numbers", then the condition of the inductive common assumption is satisfied.

If 0 is also considered a natural number, then the axiom 1 is replaced by 0.

Because df is parallel to be, so Sun Fengbu is equal to the angle bef angle DFE, the base is noisy, so the angle AEB angle DFC, there is because AB is parallel to CD, so the angle EAB angle DCF, AB and CD, so the triangle AEB is all equal to the three spike angle DCF, so AE CF
