Determine whether each first-order differential equation is separable, linear, both, or neither.

---

choose one Separable Linear Both Neither 1. $\displaystyle \frac{dy}{dx}+e^x y = x^2y^2$

choose one Separable Linear Both Neither 2. $\displaystyle y + e^x \sin x = x^3 y'$

choose one Separable Linear Both Neither 3. $\displaystyle \ln x - x^2 y = x y'$

choose one Separable Linear Both Neither 4. $\displaystyle \frac{dy}{dx} + \cos y = \tan x$
