General Solution of a Differential Equation
A general solution of a differential equation is a solution that encompasses all possible solutions to the equation, including particular solutions and a family of solutions. It provides a complete description of the possible trajectories of the dependent variable.
Particular Solution of a Differential Equation
A particular solution is a specific solution that corresponds to a particular initial condition. By evaluating the general solution at the initial condition, we obtain a unique solution that describes the particular trajectory of the dependent variable.
Key Difference Between General and Particular Solutions
General solutions describe all possible solutions, while particular solutions correspond to specific initial conditions.
General solutions may contain arbitrary constants, while particular solutions do not.
Particular solutions can be found by evaluating the general solution at specific initial conditions.
Examples
General solution:
Particular solution 1 (constant initial condition):
Particular solution 2 (zero initial condition):
Note:
The general solution to a differential equation may not be unique. Depending on the initial conditions, there may be multiple particular solutions
