Python | Numpy np.chebmul() method

With the help of np.chebmul() method, we can get the multiplication of two Chebyshev series by using np.chebmul() method.

Syntax : np.chebmul(s1, s2)
Return : Return an array after multiplication.

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