Can someone help me solve a and b

7. Find the inverse Laplace transform of the given functions; in other words, find the function whose Laplace transform is shown. (4 pts each) 2s 3 a. FO= b. G(s) = 82 -9 S- 2Definition: The Laplace Transform of a function, f(), for 20 is defined as: c(f (1) = [est f(t) dt; for all s where the integral is convergent. f(t) c(f()} = F(s) ($ >0) (s >0) (s >0) 1 (s > a) s - a S cos(kt) ( s > k ) k sin(kt) ( s > k) cosh(kt) S (s > k) k sinh(kt) $2 - K2 ( s > k )
