Question

integration of infinity to zero e^-st.b dt ... guys please give answer​

Answer 1

Answer:

This is Laplace transform example.

We know that, cos(t)=(e^(it)+e^(-it))/2

Write this in above equation and you can easily observe that it looks similar to Laplace transform of t^3 only in which ‘s’ will be modified to (s-i) and (s+i) in two terms. All you need to do then is just simplifications.
