## Main Question or Discussion Point

Hi,

I'm doing some preparation work for an upcoming mathematics module at University and I'm going over some Laplace transform questions.

Part of one question asks for the Laplace transform of sin(ωt – Φ) and after looking the transform up I've found the answer to be (ω)cos(Φ) + (s)sin(Φ) / (S^2 + ω^2).

Can anyone please tell me how to get there, because after attempting to transform using the normal method of integrating the function multiplied by e^-st I keep on hitting incorrect anwers.

Many thanks to anyone who can help me out with this - it's driving me crazy!
