Another lovely short example - thank you!

Is there anything wrong with putting the answer in the form u(t-1)(1 - cos(t-1) )?

I saw Y(s) = [e^-s/s] * [1/(s^2+1)] and immediately thought "Aha, product of two transforms again - it's the convolution of u(t-1) and sin(t)!!" Shall have to go off and do some reading.
