Question

s/((s+a)^2+w^2)^n inverse Laplace transform

Answer 1

e^-at(cos(Wt))-(a/W^2)e^-at((sinwt))

Answer 2

sprry the second part is just a/w not w squred

Answer 3

the answer is t^k*e^-at*sin(wt)c
iwant to know what is the value of c and k and how i can find it by using the partial fraction expansion with details
