Hello, could I get some help with this Differential Equations question?

  • Use Laplace transform to solve the initial value problem.
  • Express y as a piecewise function of the form y = [] if 0 <= t < pi/2 and [] if t >= pi/2.

Thank you!

The equation provided is a second-order linear differential equation with initial conditions and is given below:

\[ y'' + 2y' + 5y = \delta\left(t - \frac{\pi}{2}\right), \quad y(0) = 1, \quad y'(0) = 0.\]

Where:
- \(y\) is the unknown function of time \(t\).
- \(y'\) is the first derivative of \(y\) with respect to \(t\).
- \(y''\) is the second derivative of \(y\) with respect to \(t\).
- \(\delta\left(t - \frac{\pi}{2}\right)\) is the Dirac delta function, which introduces an impulsive force at \(t = \frac{\pi}{2}\).
- The initial conditions are given as \(y(0) = 1\) and \(y'(0) = 0\).

This equation can be analyzed using various methods such as Laplace transforms to find the solution \(y(t)\). The Dirac delta function \(\delta(t - \frac{\pi}{2})\) indicates that there is an impulse at time \(t = \frac{\pi}{2}\).

In practical applications, such an equation could model a system where an instantaneous force or signal is applied at a specific time, and we are interested in understanding the system's response considering the initial conditions.
