DP Mathematics | Legacy SL Booklet 27 | Original 26-page PDF

Original 26-page legacy teaching booklet by Dr Taylan Çeltik, headed Y13-SL.WEEK-27. It contains trigonometric differentiation and integration, vector equations of lines, intersections, angles, unit vectors and examination-style vector problems.

This historical SL label predates the current AA syllabus. The 3D vector work is now AA HL content. Question 27-14 on pages 19–20 matches the recording, including the line with direction (2,m,2m). The corresponding current HL Booklet 25 exercise changes that direction, so it is not interchangeable for that part.

Includes the unchanged original PDF plus a separate one-page clarification sheet for identified sign/answer errors. Original question numbers, diagrams, handwritten notes and selected scanned solutions are retained. Some scans are light; zoom the PDF for details. This is not a newly authored edition or a complete worked-solutions pack.
