Question 02 (Textile Engineering & Fibre Science)

The Laplace transform e^{-t}cos(2t) is

[Show Answer]

Write Here

Laplace transform of cos(at) is \frac{s}{s^2+a^2}
Laplace transform of e^{-bt}cos(at) is  \frac{s+b}{(s+b)^2+a^2}
Now Laplace transform of e^{-t}cos(2t) is-
\frac{s+1}{s^2+2s+5} (Ans)
