The image contains two mathematical problems:

### Problem 1:
The problem asks to find the Laplace Transform of a function \( f(t) \) given by the following integral:
\[
\mathcal{L}\{f(t)\} = \int_0^{\infty} e^{-st} \left( \int_0^t u(t-\tau) \cdot f(\tau) \, d\tau \right) dt
\]
where \( u(t) \) is the unit step function.

### Problem 2:
This is the integral expression for the Bessel function of the first kind:
\[
J_n(z) = \frac{1}{\pi} \int_0^\pi \cos(n\tau - z\sin\tau) \, d\tau
\]

These problems require applying specific techniques in Laplace transforms and understanding Bessel functions, respectively.

### Tip:
For solving integrals involving special functions like Bessel functions, it is often useful to recognize standard forms and use known integral representations or tables.

Find the Laplace Transform of a function f(t) given by the following integral: L{f(t)} = ∫₀^∞ e^{-st} [∫₀^t u(t-τ) ⋅ f(τ) dτ] dt, where u(t) is the unit step function. Additionally, express the Bessel function of the first kind using the integral: Jₙ(z) = 1/π ∫₀^π cos(nτ - zsinτ) dτ.
