Ordinary Differential Equations (ODEs) are essential for modeling physical and engineering systems. The Laplace Transform provides a systematic methodology to convert complex differential equations into simpler algebraic forms. This approach includes obtaining solutions in the complex domain and then converting back to the time domain with inverse transformations, streamlining the solution process significantly for engineers.

Term: Laplace Transform
Definition: An integral transform that converts a function of time (t) into a function of a complex variable (s), facilitating the easier solving of differential equations.
Term: FirstOrder ODE
Definition: A differential equation involving an unknown function and its first derivative, often expressed in the form dy/dt + P(t)y = Q(t).
Term: SecondOrder ODE
Definition: A differential equation that includes the second derivative of the unknown function, typically used in system dynamics applications.
Term: Initial Conditions
Definition: Values that specify the state of a system at the initial time, crucial for finding unique solutions to differential equations.
Term: Partial Fraction Decomposition
Definition: A technique used to break down complex rational functions into simpler fractions, aiding in the inverse Laplace transform process.
