Question

Solve the following initial value problems by using Laplace transforms:
I did attached the question and the answer based on a calculator that I used. Please write neatly.

x' (t) + 4x' (t) = −2t – sin(t – 4), with x(4) = 0, and x'(4) = 1.
Transcribed Image Text:x' (t) + 4x' (t) = −2t – sin(t – 4), with x(4) = 0, and x'(4) = 1.
laplace transform.x + 4x = -2t-sin(t-4), x(4) = 0, x' (4) = 1
