Differential equations with complex roots

WebWe learned that if the roots of our characteristic equation are r is equal to lambda plus or minus mu i, that the general solution for our differential equation is y is equal to e to the … WebThe two roots of our characteristic equation are actually the same number, r is equal to minus 2. So you could say we only have one solution, or one root, or a repeated root. However you want to say it, we only have one r that satisfies the characteristic equation. You might say, well that's fine.

WebSo let's write down the characteristic equation. So it's r squared plus 4r plus 5 is equal to 0. Let's break out our quadratic formula. The roots of this are going to be negative b. So minus 4 plus or minus the square root of b squared. So that's 16. Minus 4 times a-- well that's 1-- times 1, times c times 5. WebMay 1, 2015 · After solving the characteristic equation the form of the complex roots of r1 and r2 should be: λ ± μi. We refer back to the characteristic equation, we then assume that all the solution to the differential equation will be: y(t) = e^(rt) By plugging in our two roots into the general formula of the solution, we get: y1(t) = e^(λ + μi)t
