Where D_1 and D_2 are real numbers.
]]>So you'd get the equation
Where the particular solution can be solved with the approach
And you could always rewrite the homogenous solution with exponentials and sin/cos instead of expoentials with i if that makes it easier.
]]>So the homogenous solution is
Ok, I see it. I doubt you're supposed to get imaginary numbers here. Even if we neglect k and set it as 1 instead of 0, we'd get imaginary numbers anyway. have you encountered imaginary numbers such as i before?
I could try solve it anyway if you want, but if you haven't encountered numbers such as i before, I don't think this is correct. It depends on who gave you this problem though
I'm having some problems with understanding the problem, english is not my native language, but I guess the equation becomes (with k being zero):
Could we simply take F(t) = (1/2)cos(4t) above? If so, I could solve for y. I just want to make sure things gets right.
