Question

Find the L(t+sin(2t)).

(a) \(\frac{1}{s}+\frac{2}{(s^2+4)}\)

(b) \(\frac{1}{s}+\frac{3}{(s^2+4)}\)

(c) \(\frac{1}{s}+\frac{2}{(s^2+2)}\)

(d) \(\frac{2}{s}+\frac{2}{(s^2+4)}\)

I have been asked this question during an interview.

I need to ask this question from Table of General Properties of Laplace Transform topic in chapter Laplace Transform of Engineering Mathematics

Answer 1

Right option is (a) \(\frac{1}{s}+\frac{2}{(s^2+4)}\)

To explain I would say: In the given question,

L(t+sin⁡(2t))

=\(\frac{1}{s}+\frac{2}{(s^2+4)}\).
