Watch a video lesson on how to solve first order homogenous equations, a type of differential equations, with examples and exercises. A first order homogeneous linear differential equation is one of the form. y˙ p(t)y = 0 (17.2.1) (17.2.1) y ˙ p (t) y = 0. or equivalently. y˙ = −p(t)y. (17.2.2) (17.2.2) y ˙ = − p (t) y. "linear'' in this definition indicates that both y˙ y ˙ and y y occur to the first power; "homogeneous'' refers to the zero on the right hand. A first order differential equation is homogeneous when it can be in this form: dy dx = f ( y x ) we can solve it using separation of variables but first we create a new variable v = y x. v = y x which is also y = vx. and dy dx = d (vx) dx = v dx dx x dv dx (by the product rule) which can be simplified to dy dx = v x dv dx.
Solving First Order Homogeneous Differential Equations With Exam A first order homogeneous linear differential equation is one of the form. y˙ p(t)y = 0 (17.2.1) (17.2.1) y ˙ p (t) y = 0. or equivalently. y˙ = −p(t)y. (17.2.2) (17.2.2) y ˙ = − p (t) y. "linear'' in this definition indicates that both y˙ y ˙ and y y occur to the first power; "homogeneous'' refers to the zero on the right hand. A first order differential equation is homogeneous when it can be in this form: dy dx = f ( y x ) we can solve it using separation of variables but first we create a new variable v = y x. v = y x which is also y = vx. and dy dx = d (vx) dx = v dx dx x dv dx (by the product rule) which can be simplified to dy dx = v x dv dx. The chain rule is used to differentiate the right hand side: dy dx = dv dx ⋅ d dv(1 v), dy dx = − 1 v2 dv dx. substituting this and y = 1 v into the original differential equation gives: x(− 1 v2 dv dx) 1 v = x(1 v)2. here some cancellation is possible, and the remaining equation will be of a form which can be solved. Differential equations relate a function to its derivative. that means the solution set is one or more functions, not a value or set of values. lots of phenomena change based on their current value, including population sizes, the balance remaining on a loan, and the temperature of a cooling object.
