Question

Solve laplace transform tsin (2t+3)

Answer 1

Answer:

My question is use L(f′(t))=sF(s)−f(0) to show that L(sin2(t))=2/(s2+4).

My approach was to integrate sin2(t) to find f(t), then use this to find F(s) and f(0).

However, using that method, I find that the Laplace transform of sin2(t) is (s/2−1/2(s/(s2+4)), not 2/(s2+4).

hope I can help u
