Problem 2. Find the Laplace Inverse Transform of the following functions: -5S е (a) s(s+1)² 2 -3S (b) e (s-3)³

Part A is correct but I'm not sure about part b

Use laplace transform to solve the given initial-value problem. Graph your solution on interval (0,8pi); a) y''+y=summation from k=1 to positive infinity of alpha(t-Kpi), y(0)=0,y'(0)=1.

Determine the value of a scalar a if the following three vectors are to lie in the same plane :  A = 2i - j + 2k m , B = 6i +3j +ak m and C = 16i + 46j + 7 k m.
