terms of cosine

Given the following functions F

 

(s), find f(t). Note: Derive an expression in terms of cosine with a phase angle as discussed in the text, rather than using both cosine and sine functions. The form with a single trigonometric function is much more useful in practice as it shows the phase behavior more clearly.

 

(a)  F(s) = s(s + 3)
(s + 7)(s2 + 6s + 18)

 

(b)  F(s) = (s + 5)(s + 11)
s(s2 + 8s + 32)

 


(a) Find f(t) at t = 1.
(b) Find f(t) at t = 1.

*****NOTE******* From a previous wrong answer I know that the answers are in decimal form, for ex...On my previous attempt the answers were "a) 0.000013698072" and "b) 0.733145703655"
