![Evaluate the definite integral:
\[ \int_{0}^{1} \frac{e^x}{1 + e^{2x}} \, dx. \]
In this problem, we'll be evaluating the given definite integral from 0 to 1 of the function \(\frac{e^x}{1 + e^{2x}}\).
### Solution Steps
1. **Simplify the Integrand**: Start by examining if any simplification or substitution can be applied to make integration easier.
2. **Substitution Method**: If applicable, perform a substitution to transform the integral into a simpler form.
3. **Integration**: Integrate the resulting function concerning the new variable.
4. **Reverse Substitution**: Convert back to the original variable if substitution was used.
5. **Evaluate the Definite Integral**: Apply the limits of integration to find the value of the definite integral.
### Integral Techniques
Possible techniques include substitution, integration by parts, or recognizing the integrand as a derivative of a known function.
By carefully following these steps, you can evaluate the integral accurately.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F966b9752-0e6e-47d7-af8f-ce4bbf704a72%2F5ccd0920-9ba5-43cd-8129-31d2e876857b%2Fz9jio1_processed.png&w=3840&q=75)
