It seems like your question is incomplete or missing some details. However, from what you've shared, it appears you're asking for the solution $y(t)$ of an initial-value problem (IVP). Typically, an IVP consists of a differential equation along with initial conditions. Here is the general structure of such problems:

1. Differential Equation: An equation involving derivatives of a function (e.g., $\frac{dy}{dt} = f(t, y)$).
2. Initial Condition: A given value for the function and/or its derivative at a specific time $t_0$, e.g., $y(t_0) = y_0$.

Could you provide the full differential equation and any initial conditions?

Let me know, and I'd be happy to solve the problem!
