Legacy SL Booklet 31 - Trigonometry and Function Graphs | Original PDF

Download Dr Taylan Çeltik’s unchanged original 26-page legacy SL Booklet 31. This is the historical teaching edition, rather than a newly rewritten companion. All original question numbers, mathematical data, equations, diagrams and selected handwritten solutions are retained.

Trig identities, square roots and domains, double angles and exact values, signed/coterminal angles, finite-interval equations, general solution families, and qualitative function/derivative graphs. General integer-parameter trig solutions are AA HL/enrichment beyond present AA SL requirements.

Included files: the original 26-page booklet PDF and a separate 2-page clarification PDF. Read the notes for principal-root signs, the missing square in Q31-3(f), the quadrant-II sign in Q31-5, the literal-domain range in Q31-13, the undetermined sign in Q31-19 and the absolute value needed in Q31-23. Original questions and recordings retain their historical form; these separate notes explain the identified corrections.

The original includes selected answers and scanned working, not a complete worked-solutions pack. Some inherited scans are softer than typed pages. Historical examination notes do not replace current IB guidance. Follow each video’s current syllabus scope and question references; topics are connected through a spiral learning approach. Digital PDF downloads only.
