Here are the key Differential Equations formulas and principles relevant for JEE Main:

 1. Basic Concepts

- A differential equation involves derivatives of a function. For example, $\dfrac{dy}{dx} = f(x)$.

- Order: The highest derivative in the equation.

- Degree: The power of the highest derivative, provided it is a polynomial in derivatives.

 2. General Solution and Particular Solution

- General Solution: A solution containing arbitrary constants.

- Particular Solution: A solution obtained by assigning specific values to the arbitrary constants.

 3. Types of Differential Equations

 First-Order Differential Equations

1. Separable Differential Equations:  

   - Form: $\dfrac{dy}{dx} = g(x)h(y)$

   - Solution: Separate variables and integrate:

     \[\int \dfrac{1}{h(y)} \, dy = \int g(x) \, dx\]

2. Homogeneous Differential Equations:  

- Form: $\dfrac{dy}{dx} = f\left(\dfrac{y}{x}\right)$

- Solution: Substitute $ y = vx $ (where $ v = \dfrac{y}{x} $), then solve by separation of variables.

3. Linear Differential Equations:  

   - Form: $\dfrac{dy}{dx} + P(x)y = Q(x)$

   - Solution: Use the integrating factor (IF), given by:

     \[\text{IF} = e^{\int P(x) \, dx}\]

   - Then, the solution is:

     \[y \cdot \text{IF} = \int Q(x) \cdot \text{IF} \, dx + C\]

4. Exact Differential Equations:  

   - Form: $ M(x, y) \, dx + N(x, y) \, dy = 0 $

   - Condition: $ \dfrac{\partial M}{\partial y} = \dfrac{\partial N}{\partial x} $

   - Solution: Find a function $ \psi(x, y) $ such that $ d\psi = M \, dx + N \, dy $.

 4. Second-Order Differential Equations with Constant Coefficients

- Form: $ a \dfrac{d^2y}{dx^2} + b \dfrac{dy}{dx} + c y = 0 $

- Auxiliary Equation: $ ar^2 + br + c = 0 $

- If roots $ r_1 $ and $ r_2 $ are real and distinct:

    \[y = C_1 e^{r_1 x} + C_2 e^{r_2 x}\]

- If roots $ r_1 = r_2 = r $ (real and equal):

    \[y = (C_1 + C_2 x)e^{r x}\]

- If roots are complex $ r = \alpha \pm \beta i $:

\[y = e^{\alpha x} (C_1 \cos \beta x + C_2 \sin \beta x)\]

 5. Formation of Differential Equations

- To form a differential equation from a family of curves, differentiate the given equation as many times as there are arbitrary constants, and then eliminate these constants.

 6. Solution of Differential Equations by Substitution

- Clairaut’s Form: For equations of the form $ y = x \dfrac{dy}{dx} + f\left(\dfrac{dy}{dx}\right) $, find solutions by differentiating or substituting accordingly.

 7. Applications of Differential Equations

1. Growth and Decay: $\dfrac{dy}{dt} = ky$, where $k$ is the growth/decay constant.

   - Solution: $ y = y_0 e^{kt} $

2. Newton’s Law of Cooling: $\dfrac{dT}{dt} = -k(T - T_{\text{env}})$, where $T_{\text{env}}$ is the environment temperature.
