I am studying Control Theory from Ogata. My math is a little rusty, so this is a math question about Frequency Domain Analysis.

I get everything upto Equation 8-4
However I don't get the line after that.
The line "where the constant a can be evaluated from Equation (8-2) as follows"
And they write the value of a.
How is
a = G(s) (ωX) /(s^2 + ω^2).
How do they arrive at this value of a?
Can someone help?
And why did they substitute s = -jω after that?
