First-Order Linear ODE Steps. LDE has many applications in engineering problems.

Use the exactness . A first order linear differential equation is a differential equation of the form y ′ + p (x) y = q (x) y'+p(x) y=q(x) y ′ + p (x) y = q (x).The left-hand side of this equation looks almost like the result of using the product rule, so we solve the equation by multiplying through by a factor that will make the left-hand side exactly the result of a product rule, and then integrating. Then put back value of u = f(y). . Change y (x) to x in the equation. :) https://www.patreon.com/patrickjmt !! In this section we solve linear first order differential equations, i.e. A differential equation of the form. 2 Cauchy-Euler Differential Equations A Cauchy-Euler equation is a linear differential equation whose general form is a nx n d ny dxn +a n 1x n 1 d n 1y dxn 1 + +a 1x dy dx +a 0y=g(x) where a n;a n 1;::: are real constants and a n 6=0.
