Hope any smart friends help me with this python code? Thanks a lot!!!

5. Chebyshev polynomials a. Write a function that returns the value of the Chebyshev polynomial Tfor any integer n0 and any E R. Use the recursion relation (rather than the cosine formula), and write a recursive function. This approach gives the correct answer for all a, not just a e-1,1 In def cheb_poly(n,x) b. Plot T, (z) for n = 1, 2, 3, 4, 5 on a single plot with-1 1. (Don't bother plotting To (z), which is equal to 1.) z In [ ]
