Differential equations are like roller coasters of change. They describe how things evolve over time, from the motion of a pendulum to the population growth of a species. Let’s unravel their mysteries:

• Derivative: The speedometer that measures how fast things change.
• Differential Equation: The equation that governs the roller coaster ride, guiding how a quantity changes over time.
• Fundamental Solutions: The building blocks that form the backbone of solutions to differential equations.
• Independence of Solutions: The harmony among different solutions, ensuring they don’t crash into each other.
• Solvability of Differential Equations: The quest to find the Holy Grail, the solution to differential equations.
• Stability of Solutions: The secret to understanding how dynamical systems behave, predicting whether solutions soar or spiral out of control.
