Hey guys, I was doing some homework problems and I ran into a problem regarding how to solve a certain improper integral.
[tex]\int e^{t*(b-s)}[/tex] evaluated from 0 to [tex]\infty[/tex]
So I take the integral and get
[tex]\frac{\int e^{t*(b-s)}}{-(b-s)}[/tex] which evaluated from 0 to [tex]\infty[/tex]
gives me 0 - [tex]\frac{1}{-(b-s)}[/tex]
which is 1/(b-s)
The answer should be 1/(s-b). Can anyone help me figure out what I am messing up?
