520 _aThe justification for the adoption of a new book on trigonometry should not be based simply on its authorship by Filipino writers. The new textbook must have other qualities if it is to avoid being recognized as an imposition in the classroom. One of the requisites for an acceptable textbook is that it must be expressed in language which is readily understood by its reader.
