Trig Expression Simplify
1. **State the problem:** Simplify the expression $$\frac{1+2\cos x \sin x}{\cos x \sin x + \cos^2 x}$$.
2. **Rewrite the numerator:** The numerator is $$1 + 2\cos x \sin x$$.
3. **Rewrite the denominator:** The denominator is $$\cos x \sin x + \cos^2 x$$.
4. **Use trigonometric identities:** Recall that $$\sin(2x) = 2\sin x \cos x$$, so $$2\cos x \sin x = \sin(2x)$$.
5. **Rewrite numerator using identity:** Numerator becomes $$1 + \sin(2x)$$.
6. **Factor denominator:** Factor out $$\cos x$$ from the denominator:
$$\cos x \sin x + \cos^2 x = \cos x (\sin x + \cos x)$$.
7. **Rewrite the expression:**
$$\frac{1 + \sin(2x)}{\cos x (\sin x + \cos x)}$$.
8. **Final simplified form:** The expression is simplified to $$\frac{1 + \sin(2x)}{\cos x (\sin x + \cos x)}$$.
This is the simplified form unless further context or constraints are given.
