Question

This is a classical wave equation problem and I am struggling with the integration part of it. we have a string fixed on both ends and a velocity profile at time 0 where v= (2v0/L) x from 0 to L/2, and (2v0/L)(x-L) from L/2 to L. Picture attached is the integration I'm struggling with.

The image contains a mathematical expression involving integrals and trigonometric functions. The expression is composed of two definite integrals. Here is the transcription:

\[ 
\int_{0}^{\frac{9}{2}} \left( \cos \frac{\pi n}{2} x \right) \frac{2\sqrt{2}}{e} \, dx + \int_{\frac{9}{2}}^{e} \left( \cos \frac{\pi n}{2} x \right) \frac{2\sqrt{2}}{e} x \, dx 
\]

Explanation:

1. **First Integral:**
   - Integral from 0 to 9/2.
   - Integrand: \(( \cos \frac{\pi n}{2} x ) \frac{2\sqrt{2}}{e}\).

2. **Second Integral:**
   - Integral from 9/2 to \(e\).
   - Integrand: \(( \cos \frac{\pi n}{2} x ) \frac{2\sqrt{2}}{e} x\).

This expression involves cosine functions scaled by a fraction and additional linear terms. It illustrates the setup of a composite integral with differing bounds and integrands.
