20.06.2017 · 3. This answer is not useful. Show activity on this post. The standard way of solving this type of equation would be to notice it is a linear differential equation: d y d x − 1 x ⋅ y = x. So, the integrating factor here is e ∫ − 1 x d x = 1 x, and we can write. 1 x d y d x − 1 x 2 y = 1. d d x ( y x) = 1. y x = x + c.
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. Theorem 1.9.3 The general solution to an exact equation M(x,y)dx+N(x,y)dy= 0 is defined ...
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 ...
