The vertical displacement d d\,d of a point on a rotating wheel is given by d=sinθ∘d = \sin \theta^\circd=sinθ∘, where θ \theta\,θ is the angle of rotation.
Sketch the graph of d d\,d against θ \theta\,θ for −180≤θ≤180-180 \leq \theta \leq 180−180≤θ≤180.
On the coordinate system provided, sketch the graph of d=sinθ∘d = \sin \theta^\circd=sinθ∘ for −180≤θ≤180-180 \leq \theta \leq 180−180≤θ≤180.
