Consider the differential equation
where I''+I=e^it where i= sqrt (-1)
So I don't know what to do. I do know that The second derivative of
c*t*e^(i*t) is
-c e^(i t) (-2 i+t)
But I don't know what to do for a and b and I need help to get threw this problem before I take my test...
Help! Thrid second and first order differential equation!
I have no idea how to accomplish this problem. If anyone knows help please help me solve this example before I take my test!
Solve
y''' - y'' - y' + y - x = 0
