What are the applications of non exact differential equation?
Non-exact differential equations are commonly applied in various fields such as physics, engineering, and economics. They can model systems where the relationship between variables is not straightforward, such as in fluid dynamics, where viscosity and turbulence complicate the equations. Additionally, they are used in control theory to describe dynamic systems that do not follow exact relationships, and in thermodynamics to analyze processes that involve non-conservative forces. Their solutions often provide insights into complex phenomena that require approximations or numerical methods.
