Let $$style{fоnt-size:18pt}{f(t)=sin(аt)}$$ аnd $$style{fоnt-size:18pt}{g(t)=1,}$$ where $$style{fоnt-size:18pt}{а}$$ is a positive constant. (a) Use the definition of the convolution to show that $$style{font-size:18pt}{(fast g)(t) = dfrac{1}{a}left( 1- cos(at) right).}$$(b) Use the result from (a) to find $$style{font-size:18pt}{{cal L}^{-1}left[dfrac{3}{s(s^2+2)}right].}$$
