    Hi Fellows:

    If anyone has access to a copy of 'Differential Equations with Boundary-Value Problems (THIRD edition)' by Dennis G. Zill and Michael R. Cullen, I just need you to paste here or dictate to me on phone the following problem equations:

    1. Problem no. 12 of chapter 4 review exercise.
    2. Problem no. 23 of chapter 4 review exercise.

    I will be very, very thankful to you.

    Best Regards.

    I needed them as part of assignment. My professor was out of country.
