Trigonometry

Trig identities, graphs, and equation solving with a clear method.

Trig shows up repeatedly in Pure papers and often links into calculus.

Start with graphs and standard identities before solving harder equations.

Mixing degrees and radians or missing extra solutions in a range.

Teach me trig identities for A-Level Maths and then test me on one proof-style question.

Starter tasks

Keep the first session short and clear.

Sketch sine, cosine, and tangent over one cycle.

Prove one identity from first principles.

Solve one trig equation on a stated interval.
