Q: What is the Laplace transform of 2e^{3t}(4 cos 2t − 5 sin 2t)?
(a)(8s + 44)/(s² + 6s − 13)
(b)(4s − 44)/(s² − 6s + 13)
(c)(4s + 44)/(s² + 6s − 13)
(d)(8s − 44)/(s² − 6s + 13)
Correct Answer: (d)
The correct answer is (b) '(4s − 44)/(s² − 6s + 13)'. This question from the General Studies domain tests knowledge of Miscellaneous.
