Use the linearity of the Laplace transform to find the Laplace
transform of the function given below; a and b are real constants.
Assume that the necessary elementary integration formulas extend to
this case.
f(t)= eat sin(bt)
NOTE: Your answer should be an expression in terms of a, b, and s.
It must be fully simplified. It cannot contain i.
