Answer: Here, the value of the differential equation is, [tex]y=Acos\sqrt[]{6} +Bsin\sqrt[]{6}[/tex] Step-by-step explanation: Given that, y”+6y=0—–(i) Let, [tex]y=e^{mx}[/tex] be the auxiliary equation . Now, using (i) we can write — [tex]m^2+6=0[/tex] ⇒ m=± [tex]\sqrt[]{-6}[/tex]= ±i [tex]\sqrt[]{6}[/tex] ∴ The general solution is , [tex]y=Acos\sqrt[]{6} +Bsin\sqrt[]{6}[/tex] Reply
Answer:
Here, the value of the differential equation is,
[tex]y=Acos\sqrt[]{6} +Bsin\sqrt[]{6}[/tex]
Step-by-step explanation:
Given that,
y”+6y=0—–(i)
Let, [tex]y=e^{mx}[/tex] be the auxiliary equation .
Now, using (i) we can write —
[tex]m^2+6=0[/tex]
⇒ m=± [tex]\sqrt[]{-6}[/tex]= ±i [tex]\sqrt[]{6}[/tex]
∴ The general solution is ,
[tex]y=Acos\sqrt[]{6} +Bsin\sqrt[]{6}[/tex]
