**Homework 5** (*due 1 March*) (solution): Section 8.3: #8, 9, 11, 13, 18, 19, 25, 26, 28, 29, 37, 40, 53, 32, 35, 54, 55, 57, 59, 62

**Problem A**: The so-called Chebyshev polynomials (of the second kind), denoted by $U_n(x)$, are a special set of polynomials defined by the formula

Compute $U_1(x)$ and $U_2(x)$.

(*hint: to find, for example, $U_2(x)$, set $n=2$ in the definition and then expand using the sum identity for sine and the double angle identity for sine, as appropriate*)
