    when t<0 how we can say that u(t)=0

    eduncle-logo-app

    as given in question t>0 , so for t<0 u(t) =0 is solution ...

    eduncle-logo-app

    also given u(0)=0 so

    eduncle-logo-app

    in 2nd picture you say when t>=c; u(t) = (t-c)^4 how it's possible? We also write u(t)=(t+c)^4

    eduncle-logo-app

    taking c=-1

    eduncle-logo-app

    I think ,u have written c and d option wrong , it should be this

    eduncle-logo-app

    no sir

    eduncle-logo-app

    u(0) =0 is not satisfied by c and d option

    eduncle-logo-app

    if your question is right then then only option a and b are correct

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    but if my question is wrong so options c&d are correct

    eduncle-logo-app

    but sir how we can write u(t)=(t-c)^4

    eduncle-logo-app

    we also write u(t)=(t+c)^4

    eduncle-logo-app

    sir please contact me 7908674295

    eduncle-logo-app

    c is constant , so u can take c= -c

    eduncle-logo-app

    see this , I think your doubt is clear .. if not please ask

    eduncle-logo-app

    take c=1 in both form , u will get your answer...

    eduncle-logo-app

    see..
