A curve C C\,C has parametric equations
x=2+3cost,y=5+6cos2t0≤t≤2π x = 2 + 3 \cos t, \quad y = 5 + 6 \cos 2t \quad 0 \leq t \leq 2\pi x=2+3cost,y=5+6cos2t0≤t≤2πFind an equation for C C\,C in the form y=f(x)y = f(x)y=f(x) and state the domain for which the curve is defined.
Sketch the curve
Practise Edexcel A Level Maths Parametric Equations with exam-style questions for A Level Maths. 64 questions covering 8.1 Parametric Equations, 8.2 Using Trigonometric Identities, 8.3 Curve Sketching, 8.4 Points of Intersection, and 8.5 Modelling with Parametric Equations, matched to the Edexcel A Level Maths (9MA0) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
