__General and Particular Solution of Differential Equation__

But for differential equation like y’-sinx=0. Solution of y is in function in terms of variables not in numbers.

We classify solution of differential equation into two parts-

- General Solution
- Particular Solution

Let us understand __General solution__ of differential equation with an example.

__Example____:__

dy/dx - k sin(x) = 0 – A differential equation

Integrating both side

∫dy = ∫dx * k sin(x)

We get solution as y=-Kcosx+c

This is called a “general solution” of a differential equation as we get the solutions in constant form of K and C (k and c can be any value from - ∞ to + ∞ )

**Particular solution**:

Now the solution we get is a General solution but if we assign some value to it by giving some conditions Let’s say we get the value of k and c be -4 and 7 resp. then the equation will became

y=4cosx+7 - This equation is a particular solution of a given differential equation.
