Exact Differential Equation Questions: Question 1) Solve 3x (xy -2)dx + (x2 + 2y)dy = 0 exact differential equation solution) P = 3x (xy -2), Q = (x2 + 2y) First ∂ P ∂ y = 3x² and ∂ Q ∂ x = 3x² i.e. , ∂ P ∂ y = ∂ Q ∂ x . Also the functions and derivatives are continuous. Hence the equation is exact. Therefore the solution is given by

Concept: Homogenous equation: If the degree of all the terms in the equation is the same then the equation is termed as a homogeneous equation. Exact equation: The necessary and sufficient condition of the differential equation M dx + N dy = 0 to be exact is: \(\frac{{\partial M}}{{\partial y}} = \frac{{\partial N}}{{\partial x}}\) Linear equation: A differential equation is said to be linear ...

Oct 08, 2018 · Section 2-3 : Exact Equations. The next type of first order differential equations that we’ll be looking at is exact differential equations. Before we get into the full details behind solving exact differential equations it’s probably best to work an example that will help to show us just what an exact differential equation is.

From Table-1, the L.H.S of (1) is the exact differential d(tan−1 y x). d ( tan − 1 y x). Thus, our DE reduces to d(tan−1y x) +dx = 0 d ( tan − 1 y x) + d x = 0 Integrating, we obtain the solution as tan−1 y x +x = C tan − 1 y x + x = C However, it is very likely that we won’t be able to make out just be inspection whether the DE is exact or not.

previous example, a potential function for the differential equation 2xsinydx+x2 cosydy= 0 is φ(x,y)= x2 siny. We now show that if a differential equation is exact and we can find a potential function φ, its solution can be written down immediately.
