Let f be a piecewise continuous function on [0,T]. Define f on the whole of [0,inf) by f(t+nT) for all t and all integer n. Show that the Laplace transform if f is given by
L[f(t)] = 1/[1-exp(-sT)]*int(exp(-st)*f(t)dt,t=0..T)
By taking the Laplace transform and using the convolution theorem, obtain the solution of the integral equation
f(t) = 1+t+int[(t-u)f(u)du,u=0..t).© BrainMass Inc. brainmass.com March 4, 2021, 6:02 pm ad1c9bdddf
