Python | Numpy np.chebder() method Last Updated : 12 Dec, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report 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. Python3 1=1 # import numpy import numpy as np from numpy.polynomial import chebyshev as C x = np.array([1, 2, 3]) # using np.chebder() method gfg = C.chebder(x, 2) print(gfg) Output : [ 12.] Example #2 : Python3 1=1 # import numpy import numpy as np from numpy.polynomial import chebyshev as C x = np.array([2, 5, 7, 11]) # using np.chebder() method gfg = C.chebder(x, 2) print(gfg) Output : [ 28. 264.] Comment More infoAdvertise with us Next Article Python | Numpy np.chebval2d() method J jitender_1998 Follow Improve Article Tags : Technical Scripter Python Python numpy-polynomials Practice Tags : python Similar Reads Python | Numpy np.chebdiv() method With the help of np.chebdiv() method, we can get the division of two Chebyshev series by using np.chebdiv() method.
