Answer:
The general solution of the given differential equation
Step-by-step explanation:
Step(I):-
Given differential equation
y⁴+18y"+81y=0
⇒ (D⁴+18D²+81)y =0
The auxiliary equation
we will use formula ( a + b)² = a² + 2 a b + b²
⇒ ( m² + 9 ) ² = 0
⇒ ( m² + 9 ) ( m² + 9 ) = 0
m² + 9 = 0
The complex roots are 0± 3 i ,0 ± 3 i
<em>Step(ii)</em>:-
The complementary function
The general solution of the given differential equation
The general solution of the given differential equation

Monday = np = 750 × 0.1204 = 90.3 = 90 winners.
You have to integrate two equations, one for the case where the value in the absolute signs is negative and one for the case where the value is positive...
So you will integrate one on the interval 0 to 1 and the other on the interval from 1 to 3...
⌠-x+1 dx, x=[0,1] + ⌠x-1 dx, x=[1,3]
(-x^2/2+x)[0,1] + (x^2/2-x)[1,3]
(-0.5+1)+(4.5-3-0.5+1)
(0.5)+(2)
