Find the Laplace transform F(s)=L{f(t)} of the function f(t)=sin2(wt), defined on the interval t≥0. F(s)=L{sin2(wt)}= help (formulas) Hint: Use a double-angle trigonometric identity. For what values of s does the Laplace transform exist? help (inequalities)

a. b.  F(s) exists when s ≥ w + wi√3

Step-by-step explanation:

a. Laplace Transform of f(t) = sin²(wt)

f(t) = sin²(wt)

Using the double angle identity

sin²(wt) = {1 - cos(2wt)}/2

f(t) = [1 - cos(2wt)]/2

Now Laplace of f(t) = F(s) = L{f(t)}

= L{[1 - cos(2wt)]/2}

= 1/2L{1} -1/2L{cos(2wt)}

=

b. Range of values of s for which F(s) exists

The range of values of s for which F(s) exists is when F(s) ≥ 0

Using the quadratic formula,

So F(s) exists when s ≥ w + wi√3 or s ≥ w - wi√3

So F(s) exists when s ≥ w + wi√3

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
