[SOLVED] What the Hell. Differential Eq
Okay, so I used Method of undetermined coefficients for this one. I got a solution that when differentiated and plugged back in almost works, bit is off by a little.
When I plug back into y'=4x+3y+(-5t+6)
I get y'=...+9 not 6. So I have a feeling it has to do with my D=11/7 term... but I have no idea what.
Anyone see what I am doing wrong? Is my matrix incorrect? Or my assumption of Xp? Or neither?
Thanks
