How to solve linear first order diff eq
WebGeneral first order linear ODE. We can use an integrating factor μ ( t) to solve any first order linear ODE. Recall that such an ODE is linear in the function and its first derivative. The general form for a first order linear ODE in x ( t) is. (6) d x d t + p ( t) x ( t) = q ( t). (If an ODE has a function of t multiplying d x d t, you can ... WebJun 17, 2024 · 1 Solve the following equation. Because the degree of and its derivative are both 1, this equation is linear. 2 Find the integrating factor. 3 Rewrite the equation in Pfaffian form and multiply by the integrating factor. We can confirm that this is an exact differential equation by doing the partial derivatives. 4
