To solve the differential equation (\frac{dy}{dt} e^y = 3t^2 + 1), separate the variables by multiplying both sides by (dt) and dividing both sides by (e^y), which gives (\frac{dy}{e^y} = (3t^2 + 1) dt). Next, integrate both sides with respect to their respective variables. The left side integrates to (-e^{-y}) and the right side integrates to (t^3 + t + C), where (C) is the constant of integration. Solving for (y), you get (y = -\ln|t^3 + t + C| + D), where (D) is another constant of integration.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
