What is it, what is it? 5

There is no ...... truth and falsehood in the world

There is no black and white ...... in the world

There is no fair ......... in the world

It's not that the world is dark .........

To survive in this vast world ............ before you succeedIt's best not to pursue the "true & false" ......You'll regret ......That's how the world ......Recognize this society, and ...... it will beYou will understand what to do ......

Before you go to the light, there will be darkness ...... youWhen you go to the light, you must have experienced ...... darkness before

As long as you have light in your heart, one day you will find that piece of light ...... in the darknessFind the so-called "true & false" ......

Patience ............ will be foundYour "way" ......

The dream is the continuation of reality, and reality is the end of the dream The way i am

For you, what you believe is true, and if you don't believe it, it's false, you should believe in yourself and be bold to do it.

What is true is true, and what is fake is what is false.

What you know it to be true is true, and what you think it is fake is false.

The most important thing depends on your attitude,..

In fact, there are no absolutes in the world. It might be better to look at it differently!

The real can't be fake, and the fake can't be true.

The world is too fake. But it's too fake.

It is true to be able to step on it steadily.

You can only look up but can't catch it, and what you can't touch is fake.

Oh, this question, I also want to know.

But I like to give you a quota.

Everything in this world is fake, only fake is the most real!!

True and false, false and true, there is nowhere and there is nothing.

The question of truth and falsehood is an esoteric philosophical question, and you are advised not to pursue it.

Those who study philosophy ultimately have two results: 1. If your philosophical research is recognized by people, you become a great philosopher; 2. If your philosophical research is not recognized, you will be called a madman.

If you just want to find your own "way"... Then calm down and think about your own life plan...

The problem solving process is shown below:

This problem is solved by the partial integral method.

Its main principle is to transform the integral form, which is not easy to find the result directly, into an equivalent integral form that is easy to find the result. The commonly used partial integrals are based on the basic function types that make up the integrand, and the order of the partial integrals is organized into a formula: "oppose the power of three fingers".

They refer to five basic functions: inverse trigonometric functions, logarithmic functions, power functions, and exponential functions.

Partial Integral Problem Solving Method:

Let the functions f(x) and g(x) be continuously derivable, and find the derivative of their products, which are:

f(x)g(x)]'f'(x)g(x)+f(x)g'(x)

Find the indefinite integral on both sides of the above equation, and get:

f(x)g(x)]'dx=∫f'(x)g(x)dx+∫f(x)g'(x)dx

Yield: f(x)g(x) = g(x)df(x)+ f(x)dg(x).

Get: f(x)dg(x)=f(x)g(x)- g(x)df(x).

It's written in a more colloquial way.

Let u = f(x) and v = g(x), then the differential du = f'(x)dx、dv = g'(x)dx

Then udv=uv- vdu

The partial integral method is usually used in the form of the product of the integrand function as a power function, an exponential function, a logarithmic function, a trigonometric function, and an inverse trigonometric function; The choice of u=f(x) and v=g(x) is also the one that is easy to integrate.

The method is as follows, please comma circle for reference:

If there is help from the landslide, please celebrate.

The answer is 2 3x (3 2) + c

The specific steps are as follows:

xdx∫ x^1/2dx

2/3x^(3/2)+c

The formula for indefinite integrals staring at Mt. Mori.

1. A dx = ax + c, a and c are constants.

2. x a dx = x (a + 1)] a + 1) +c, where a is a constant and a ≠ 1

3. Spring Hunger 1 x dx = ln|x|+C4, A x Dx = 1 LNA) A x + C, where A > 0 and A ≠ 1

5、∫ e^x dx = e^x + c

6、∫ cosx dx = sinx + c

xlnxdx = (1 2) x 2lnx - 1 4) x 2 + is the integration constant.

The process is as follows:

Got:u'v=(uv)'-uv'

Both sides score: u'v dx=∫ uv)' dx - uv'dx stands for: u'v dx = uv - uv'd, this is the partial integration formula.

It can also be abbreviated as: v du = uv - u dv common integration formula:

1）∫0dx=c

2）∫x^udx=(x^(u+1))/u+1)+c3）∫1/xdx=ln|x|+c

4）∫a^xdx=(a^x)/lna+c

5）∫e^xdx=e^x+c

6）∫sinxdx=-cosx+c

7）∫cosxdx=sinx+c

8）∫1/(cosx)^2dx=tanx+c9）∫1/(sinx)^2dx=-cotx+c10）∫1/√（1-x^2) dx=arcsinx+c11）∫1/(1+x^2)dx=arctanx+c

74+(-34)=48, circle=4, square=-3, so that the two sides of the equal sign are flat.
