    1. Question from a textbook.
    I have written down the differential equations for part a) and shown part b),
    but I am unsure of how to tackle part c).

    2. This is the Question from the book

    It is a numerical integration. Start with x=1, calculate the derivatives, estimate the numbers a small time step later, continue until the fraction of remaining helium is negligible.
