Geometry & Trigonometry
IB Topic 3, complete: 3D geometry and the booklet's solids, right-triangle trig with the sine and cosine rules, elevation/depression and bearings, radian measure with arcs and sectors, the unit circle and exact values, the Pythagorean and double-angle identities, sinusoidal graphs and models, and trig equations — SL 3.1 to 3.8, taught to markscheme standard.
Builds on
Topic 2's transformations power the wave graphs (SL 3.7 is SL 2.11 with a circle attached), and Topic 2's hidden-quadratic trick returns in SL 3.8.
