Question
## Use a Series to Find the Limit

### Problem 6

**a.** \(\lim_{{x \to 0}} \frac{x \ln(1+x)}{x^2}\)

**b.** \(\lim_{{x \to 0}} \frac{1-\cos x}{1+x-e^x}\)

**Instructions:**

For each limit, use the appropriate series expansion to evaluate the limit as \(x\) approaches 0. Consider using Taylor series expansions for functions like \(\ln(1+x)\), \(\cos x\), and \(e^x\) to simplify the expressions first. Apply the limits after the expansions and simplifications to find the final value.
