Python | Numpy np.chebder() method

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

Syntax : np.chebder(series, value)
Return : Return an array having coordinates of series after differentiation.

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