Please help answer this question.

**Problem Statement:**

Determine the first three nonzero terms in the Taylor polynomial approximation for the given initial value problem.

\( y' = 4 \sin y + 5 e^{2x}, \, y(0) = 0 \)

---

**Solution Explanation:**

The Taylor approximation to three nonzero terms is \( y(x) = \boxed{\phantom{\text{______}}} + \cdots \).

**Notes:**

- The problem involves finding the Taylor series expansion of a solution to a differential equation.
- The given differential equation is first-order, involving trigonometric and exponential functions.
- The initial condition provided is \( y(0) = 0 \), which is used to determine the coefficients of the Taylor series.
- The goal is to compute and write the first three nonzero terms of the approximation.

**Important Concepts:**

1. **Taylor Series:**
   - A Taylor series is an infinite sum of terms calculated from the values of a function's derivatives at a single point.
  
2. **Initial Value Problem:**
   - A problem where the solution to a differential equation is required to satisfy a specific initial condition.

3. **Differentiation and Evaluation:**
   - Successive differentiation of the function and evaluation at the initial point is essential for building the Taylor polynomial.

This exercise is beneficial for understanding how to apply Taylor series to approximate solutions of differential equations, especially in cases involving nonlinear terms (such as trigonometric and exponential components).
