Relation of Boubaker Polynomials to Chebyshev Polynomials

Theorem
The Boubaker polynomials are a special case of the Chebyshev polynomials.

The Boubaker polynomials are related to Chebyshev polynomials and $U_n$ by:
 * $B_n \left({2x}\right) = \dfrac {4x}n \dfrac{\mathrm d}{\mathrm d x} T_n \left({x}\right) - 2 T_n \left({x}\right)$


 * $B_n \left({2x}\right) = -2 T_n \left({x}\right) + 4 x U_{n-1} \left({x}\right)$
