## Z4K4R1Y4 one year ago Show that x=Be^(µt) is a solution of mx ̈+kx=0

1. IrishBoy123

it's not. differentiate it.

2. Z4K4R1Y4

I know i differentiated it and didn't get the right answer.

3. Z4K4R1Y4

4. Z4K4R1Y4

and µ=α+jω

5. IrishBoy123

better. but have you differentiated that?? it's suddenly become more complicated!

6. Z4K4R1Y4

I'm afraid to try, but i'll give it a go.

lol! $x=B e^{µ t} \ : \ B=A e^{jϕ} \ \ : \ µ=α+j ω \\ x=A e^{jϕ} e^{(α+j ω) t}$ $x = A e^{α t+j ( ω t + \phi ) }$ looks interesting!!
