 # Integration Of Sinx

## Integration Of Sinx

Ah ... forgot the limit ... don't know what to do here ...

Let y = ln x

dy = 1 / x dx

. "sin (x) / x dx

= ÂˆÂ "Sin (and y) dy

It is a form that cannot be connected ... It is not a basic function nor does it contain the basic functions of a finite task.

Sorry ... I couldn't find the answer ...

At least not in unlimited integration.

Maybe one of the essential values ​​can be found.

It is not that the function can be expressed as the essence of many primary relative functions in which the function does not exist. It simply means that the function in question is not the primary function, and that is what it means.

Help for example ...

:)

If you look at Wolfram, the answer is C (X), this function is mainly used for this essential representation. In terms of closed form solutions [for example, without an unlimited number], there is no solution to this problem.

(Synx) / x

Math students will get x / x at the beginning of x

Study, when it is limited

xÃƒÂ '0

sin x / x = 1 The result

Then the difference sin formula x =

Cos X and Cos X = sin 'sin x. after this

The function is quickly forgotten and rarely seen by students.

A very simple, not for this simple task

There are some important features, but also

Many uses, sometimes very unexpected.

Note that the process is for everyone.

The value of x is not 0, but we also know that x is getting smaller and smaller

Low, sin x / x ratio "Supplied X is measured in radians"

1. This gives us a simple example of one

Exception: We have reduced the value of sin from 0/0 to 1.

And this definition guarantees continuity of action

x = 0.

Show our function with x and draw it to different values

X graphic results in Figure 61

Distinguish this graph from the graph of function G x = sin x:

First, the coordinates about the y axis; H f f x'x = f x for each

The value of x (in algebra, f x is an equal function,

That's because it's the easiest thing to do with this property

y = x shape

For an equal value of n). On the other hand, it is a function

g x = sin x has the property that for all x g ÂˆÃ‚Â'x = Â Â Â x'g x (NC)

Working with this property is called a strange function, for example y =

X.

Subway

For odd values ​​n) to show that f x = sin x / x is equal to

We just find that f ÂˆÃ‚Â'Â'x = sin ÂˆÃ‚Â'x / Â x'x = Â 'sin x / ÂˆÃ‚Â' x =

sinx / x = fx

Second, in contrast to the graph of sin X, wse increases and oscillates

The charge is 1'1 to 1 (ie sine)

## Integration Of Sinx

1 / x integration logics. Sync integration is coxswain. So the solution is logicscox. Integration and separation are mutual discussions.

xx 3/18 + x 5/600 + O (x 7) + permanent

## Integration Of Sinx

Please give me all the details.

Uh ... forget the boundaries ... don't know what's here ...

Let y = ln x

dy = 1 / x dx.

sin "sin (x) / x dx

= ÂˆÂ "Sin (and y) dy

It is a form that cannot be connected ... It is not a basic function nor does it contain a limited number of basic functions.

Sorry ... I couldn't find the answer ...

At least not in unlimited integration.

Perhaps an essential value estimate can be found.

It is not that a function cannot be represented as a combination of several initial related functions that the function does not exist. This only means that the function in question is not a basic function, and that is all.
