Approach Solution -2

Solution to the Differential Equation 
Given the differential equation: 
ey-x dy/dx = y(sinx + cosx)/(1 + ylogy) 
Rearrange to separate variables: 
e^(y-x) dy/dx = y(sinx + cosx)/(1 + ylogy)
 

Simplify and integrate both sides: 
∫ (1 + logy) e^y dy = ∫ (sinx + cosx) e^x dx 
Using integration by parts, the solution is: 
logy * e^y - ∫ e^y / y dy = e^x (sinx - cosx) + C 
Where C is the constant of integration.

Types of Differential Equations

There are various types of Differential Equation, such as:

Ordinary Differential Equations:

Ordinary Differential Equations is an equation that indicates the relation of having one independent variable x, and one dependent variable y, along with some of its other derivatives.

\(F(\frac{dy}{dt},y,t) = 0\)

Partial Differential Equations:

A partial differential equation is a type, in which the equation carries many unknown variables with their partial derivatives.

Partial Differential Equation

Linear Differential Equations:

It is the linear polynomial equation in which derivatives of different variables exist. Linear Partial Differential Equation derivatives are partial and function is dependent on the variable.

Linear Differential Equation

Homogeneous Differential Equations:

When the degree of f(x,y) and g(x,y) is the same, it is known to be a homogeneous differential equation.

\(\frac{dy}{dx} = \frac{a_1x + b_1y + c_1}{a_2x + b_2y + c_2}\)
