I am asking ,How to get roots In Scientific calculator.
I don't need solution.
Transcribed Image Text:Let us consider the given differential
d³y
equation d³ +2
d²y dy
+
dx² dx
=
0
The operator form of the equation is
D³ + 2D² + D = 0.
Now, the characteristic equation of the
given differential equation is,
p³ + 2p² + r = 0
The roots of the equation r = 0, −1, −1.
The solution of the equation is
y(x) = C₁ + C₂e¯ª + c3xе¯
-X
