Answer
Explanation:
Step1: Separate variables
For a first - order differential equation of the form $\frac{dy}{dx}=f(x)g(y)$, we rewrite it as $\frac{1}{g(y)}dy = f(x)dx$. Given $\frac{dy}{dx}=\frac{3\cos(x)}{e^{3y + 3}}$, we can cross - multiply to get $e^{3y+3}dy=3\cos(x)dx$.
Answer:
$\int e^{3y + 3}dy=\int3\cos(x)dx$
