Python | Numpy np.chebroots() method

With the help of np.chebroots() method, we can get the roots of chebyshev series by using np.chebroots() method.

Syntax : np.chebroots(array of coefficients)
Return : Return the array having roots of chebyshev series.

Example #1 :
In this example we can see that by using np.chebroots() method, we are able to get the roots of chebyshev series by using this method.

# import numpy
import numpy as np
import numpy.polynomial.chebyshev as cheb

# using np.chebroots() method
gfg = cheb.chebroots((2, 4, 8, 1))

print(gfg)

Output :

[-3.83265557 -0.71484143 0.54749701]

Example #2 :

# import numpy
import numpy as np
import numpy.polynomial.chebyshev as cheb

# using np.chebroots() method
gfg = cheb.chebroots((-3, 4, -5, 1, 10))

print(gfg)

Output :

[-1.02213642 -0.38135467 0.40624906 0.94724203]
