Question

Could we solve the second question (with the product)?

Suppose \( f \) and \( g \) are \( C^n \) functions with Taylor expansions denoted \( T_n(f, x_0, x) \) and \( T_n(g, x_0, x) \). Prove that \( T_n(f, x_0, x) + T_n(g, x_0, x) \) is the Taylor expansion of \( f + g \) at \( x_0 \).

Under the same hypotheses as exercise 11, show that the Taylor expansion of \( f \cdot g \) at \( x_0 \) is obtained by taking \( T_n(f, x_0, x) T_n(g, x_0, x) \) and retaining only the powers of \( (x - x_0) \) up to \( n \).
