    2. Relevant equations
    i+j+k=1, <1,1,1>


    3. The attempt at a solution

    a(t)=i+(30t^(4))j+(2e^(-t)ln(e)-2e^(-t)(1/e))k
    r(t)=(2+6t)i+(2+t^6+2t)j+(2+2e^-t)k

    Welcome to PF!

    Hi jmagic! Welcome to PF! :smile:
    i and j are correct, but the constant in k is wrong …

    hint: e0 = … ? :smile:
    Hint: 6 and ln(e) are constants, aren't they? :wink:
