    Solving Differential Equations

    My calculus is just finishing up "Differential Equations" and we have an on-line assignment. I've done all the other questions correctly except for one. It doesn't make sense to me but hopefully someone here can help.
    The question is:
    Find the solution to the differential equation:
    dz/dt = 9te(^6z)
    that passes through the origin.

    I have gotten the answer:
    z= [ln (-27(t^2) - C)]/-6
    but I can't figure out how to get C or get the appropriate answer.

    This looks like part of your on-line assessment.
