# Python | Numpy np.chebint() method

With the help of `np.chebint()` method, we can get the integration value of chebyshev series in the form of an array having value of coordinates using `np.chebint()` method.

Syntax : `np.chebint(series, value)`
Return : Return an array having coordinates of series after integration.

Example #1 :
In this example we can see that by using `np.chebint()` method, we are able to get the integration of chebyshev series and it will return an array having coordinates of it.

 `# import numpy ` `import` `numpy as np ` `from` `numpy.polynomial ``import` `chebyshev as C ` ` `  `x ``=` `np.array([``1``, ``2``, ``3``]) ` `# using np.chebint() method ` `gfg ``=` `C.chebint(x, ``2``) ` ` `  `print``(gfg) `

Output :

```[-0.3125      0.25       -0.25        0.08333333  0.0625    ]
```

Example #2 :

 `# import numpy ` `import` `numpy as np ` `from` `numpy.polynomial ``import` `chebyshev as C ` ` `  `x ``=` `np.array([``2``, ``5``, ``7``, ``11``]) ` `# using np.chebint() method ` `gfg ``=` `C.chebint(x, ``2``) ` ` `  `print``(gfg) `

Output :

```[-0.8125     -2.125      -0.66666667 -0.47916667  0.14583333  0.1375    ]
```
