HOMOGENEOUS EQUATION
Determine the solution of the following differential equations.
a) y"- 6y'+ 9y = 0.
b) 4y"- 12y'+ 9y = 0, y(0) = 2 and y'(0)= - 1.
c)_4y"+ 4y'+ y= 0, y(0) = 2_and_y'(1)= e ¹².
d) y"+ 16y= 0.
e) y"- 8y'+ 17y= 0, y(0)= - 4 and y'(0)= - 1.
f) y"- 4y'+ 9y= 0, y(0) = 0 and y'(0) = - 8.
a)
y(x)= (A+ Bx)e³x.
y(x)= 2(1-2x)e²¹.
y(x) = (4x + 2)e ²*.
Answers:
y(x)= Acos(4x) + B sin(4x).
y(x)= e(- 4 cos x + 15 sin x).
