I tried doing this problem soooo many times for several days and keep failing and then I'm so worn out I can't keep thinking straight and I can't move on because of this! I'm attaching my work and it would be great if I can get back and forth feedback if necessary to find my mistake(s).
The question is:
"Solve the initial value problem: y'' + 18y' + 90y = -6e^(-9t) cos(2t); y(0) = 3, y'(0) = -1"
Any help would be GREATLY appreciated!
Thanks in advance!
