First order differential equation Linear equations and integrating factors One of the most important and most common types of equations are the linear first order differential equations. A first order equation is linear if we can put it into the following form (Lebl, 2022): (7)y′+p(x)y=...
I. Equations with separable variablesFrom the past learning, we have already known that a first-order differential equation in the form of: \frac{\mathrm{d} y}{\mathrm{d} x} = f(x) g(y) can be solve…
This is a first-order differential equation in ii. The circuit is referred to as an LRLR circuit. Next, suppose there is no inductor in the circuit, but there is a capacitor and a resistor, so L=0,R≠0L=0,R≠0, and C≠0C≠0. Then y=1μ(x)[∫μ(x)q(x)dx+C]y=1μ...
