Answer:
Disvrete
Step-by-step explanation:
Answer:
3 + -5 = -2 because adding a negative is basically subtracting.
So 3 + -5 = 3 - 5 = -2
Distribute
8-2t-2=-3t+1
Combine like terms
-2t+6=-3t+1
Add 3t to both sides
t+6=1
Subtract 6 from both sides
t=-5
Final answer: t=-5
Answer:
the first choice
x=3
Answer:
Step-by-step explanation:
The equation is a<em> </em><em>linear differential equation: y⁽⁴⁾- y = 0 </em>
We assume the form of the solution y(t) is
where are the roots of the auxiliary equation.
So, use the auxiliary equation: to find the roots; the values are : α₁ = 1, α₂ = -1, α₃ = i, α₄ = -i
Then inserting values in the assumed solution
⇒ <em></em>
Also, because the last 2 terms have complex power, the solution can be written with cosine and sine terms:
<em>Using the Euler's formula: , we can rewrite the solution as:</em>
=
<em>Where: </em>
<em>Finally the solution for de linear differential equation y^(4) - y =0 is:</em>
