### Implicit and Logarithmic Differentiation Problems

#### Problem 8

Consider the curve given by:
\[ x^3 + x^2y + y^3 = 1 \]

- **Task**: Use implicit differentiation to find the equation of the tangent line to this curve at the point \( (3, -2) \).

#### Problem 9

Use logarithmic differentiation to find the derivative of:
\[ y = \frac{x^{\sin x} \sqrt{1 + x^2}}{(1 + e^{2x})^3} \]

- **Note**: You must use logarithmic differentiation correctly to get full credit. 

### Explanation

**Implicit Differentiation**:
- A technique used when differentiating equations not expressed explicitly in terms of one variable. It is especially useful for curves described by an equation involving the variables in a complicated way.

**Logarithmic Differentiation**:
- A method that simplifies the differentiation of expressions involving products, quotients, or powers by taking the natural logarithm of both sides before differentiating.
