Y10 Core Booklet 13 – Bar Charts and Trigonometry | Original 41-page PDF
Download Dr Taylan Çeltik’s unchanged original 41-page booklet, preserving the historical questions, diagrams, original page and exercise numbers, and included worked scans.
Frequency tables, mean, median, mode and bar charts; Pythagoras’ theorem, right-triangle trigonometry, bearings and triangle areas. The original includes practice questions and selected handwritten worked examples. Digital PDF download only. This is the historical teaching original, rather than a newly authored complete solutions pack.
Original-edition clarifications:
• Page 29: The instruction says 20.5 m to 2 significant figures. From 42 tan(26°), BD = 20.4847687… m, which is 20.5 m to 3 significant figures (or 2.0 × 10¹ m to 2 significant figures). Retain unrounded values for subsequent calculations.
• Page 38, 40: The worked scan reverses the two east/west bearings. C from A is 090°; A from C is 270°.
• Page 39, 41: B is north-west of C. The bearing of B from C is 270° + arctan(5/12) = 292.6198649…°, approximately 292.6° (or 293° to the nearest degree), rather than the scanned 67.4°.
• Page 38, 39: The original repeats the label (c), and some answer labels on the continuation page retain (c) inside part (d). Follow the actual wording; original labels are preserved.
The original historical cover and footer labels are retained. Where the cover says Week, it is catalogued as a Booklet for channel consistency. Each recording may cover only part of this complete original; its description identifies the actual questions taught.
