Find a particular solution for the following equation: y"+2y'+y=12.5e-t I'm not sure on which method to use. Here's my attempt using the undetermined coefficients method: →y"+2y'+y=12.5e-t r2+2r+1=0 r=-1 *not even sure if this part is useful →yp=e-t yp'=-e-t yp"=e-t...

Ahh yes And that did it. Thanks man, I ended up with λ1=-2,λ2=1, and λ3=5, which is the correct answer. Really appreciate the help.

[b]1. The 3x3 Matrix A=[33, -12, -70; 0, 1, 0; 14, -6, -30] has three distinct eigenvalues, λ1<λ2<λ3. Find each eigenvalue.[b]2. det(A-λI)=0 where I denotes the appropriate identity matrix (3x3 in this case)[b]3. Here's my attempt: --> det([33, -12, -70; 0, 1, 0; 14, -6, -30]-λ[1, 0, 0; 0, 1...
