What is in mathematical text
The trails have 30 new classes: three preparatory classes for Elementary I, six for Elementary II and 21 for High School. The classes at the last two levels develop the themes of the 51 items of the theoretical summary of the reference volume, with definitions, LaTeX formulas, demonstrations and commented exercises.
This is a didactic rewriting of the themes. The full version — theory with all demonstrations, all exercises with resolution or answers and entrance exam tests — is in the interactive Trigonometry book.
