In a theoretical study, this section contains the basic equations and the method of solution. This section should contain all the information necessary so that an ambitious reader could duplicate the basic elements of the project. It is generally the most technical section of a report. Graphs are often an important component of this section and are discussed further below. A term paper for a class is usually of such limited scope that it rarely has an acknowledgments section.
Some reports have appendices.
They contain details that are not central to the discussion and which are not described well in easily accessible references. The reference list should emphasize quality, not quantity. Reference lists are prepared in a variety of formats. Generally, you should adopt the format of an important journal in your field. Obviously, anything that you wish to submit to a particular journal must be prepared according to the standards for that journal.
