    I wonder why only the answer of odd number question of most of the text books are given. The author do it purposely? Where can I find the even numbers questions` answer?

    I think they often do it purposely so that an instructor can assign the other half of the questions as graded homework if they wish to do so. Sometimes the full set of answers is available in a teachers'/instructors' guide that publishers will only provide to a course instructor upon written request on letterhead so that students can't get copies of it.
