Question
Find dy/dx and simplify if possible:
The given mathematical expression is:

\[ y = \ln \left( \frac{x^3 \sin x}{x^2 + 4} \right) \]

This equation represents a logarithmic function where:

- \( x^3 \sin x \) is the numerator, indicating the product of \(x\) cubed and the sine of \(x\).
- \( x^2 + 4 \) is the denominator, depicting a quadratic expression with a constant added.
- \(\ln\) denotes the natural logarithm function, which applies to the entire fraction enclosed in the parentheses.

This type of equation often appears in calculus, particularly when studying logarithmic differentiation or integration.
