Question

Ive asked this quesrion 4 times now and theyve all been wrong

has solution:
yı(t)
Y₂(t)
Entered
[e^(2*t)]*[-4*cos(2)*t-5*sin (2)*t]
At least one of the answers above is NOT correct.
=
[e^(2*t)]*[-25*cos(2)*t-21*sin(2)*t]
The system of first order differential equations:
e2t (-4 cos 2t - 5 sin 2t)
e²t (-25 cos 2t - 21 sin 2t)
Note: You must express the answer in terms of real numbers only.
[3₁
13/12
-8 y₁+2 Y2,
-52 yı + 12 y2,
Answer Preview
e²t (4 cos(2) t — 5 sin(2)t)
e²t (-25 cos (2)t – 21 sin(2)t)
y₁ (0) = -4
Y₂ (0) = -25
Result
incorrect
incorrect
