Homework Statement
y`=(xy-y^2)/x^2
The Attempt at a Solution
y` = y/x -(y/x)^2
{y/x=z , y=zx , y`=z+xz`}
-z^2=x*dz/dx
-z^2dx = xdz
what`s next ?
TNX .
A differential equation is a mathematical equation that relates an unknown function to its derivatives. It involves the use of derivatives to describe and model the relationships between different variables in a system.
The two main types of differential equations are ordinary differential equations (ODEs) and partial differential equations (PDEs). ODEs involve only one independent variable, while PDEs involve multiple independent variables.
Differential equations are used in many fields of science, including physics, biology, chemistry, and engineering. They are used to model and analyze various systems and phenomena, such as population growth, heat transfer, and motion of objects.
Differential equations have a wide range of applications, such as predicting the weather, designing electrical circuits, and analyzing chemical reactions. They are also used in fields like economics, medicine, and computer science.
No, not all differential equations can be solved analytically. Some equations may have no solution, while others may require numerical methods to approximate a solution. However, many commonly occurring differential equations have known solutions.
