 # Python | Numpy np.chebadd () method

Using the `np.chebadd() ` method, we can get the addition of two Chebyshev rows using ` np.chebadd () `.

Syntax: ` np.chebadd (s1, s2) `
Return: Return an array after addition.

Example # 1:
In this example, we can see that using ` np.chebadd () `, we can get the addition of two Chebyshev rows using this method.

 ` # NumPy import ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial ` ` import ` ` chebyshev as C `   ` s1 ` ` = ` ` (` ` 4 ` `, ` ` 6 ` `, ` ` 8 ` `) ` ` s2 ` ` = ` ` (` ` 3 ` `, ` ` 5 ` `, ` ` 7 ` `) ` ` # using the np.chebadd () method ` ` gfg ` ` = ` ` C.chebadd (s1, s2) `   ` print ` ` (gfg) `

Output:

[7. 11. 15.]

Example # 2:

 ` # NumPy import ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial ` ` import ` ` chebyshev as C `   ` s1 ` ` = ` ` (` ` 4 ` `, ` ` 6 ` `, ` ` 8 ` `, ` ` 1 ` `, ` ` 3 ` `, ` ` 5 ` `) ` ` s2 ` ` = ` ` ( ` ` 3 ` `, ` ` 5 , 7 , 2 , 4 , 6 ) ```` # using the np.chebadd () method gfg = C.chebadd (s1, s2)   print (gfg) ```

Output:

[7. 11. 15. 3. 7. 11.]
