f ( x ) = sin ( x ) {\displaystyle f(x)=\sin(x)} g ( x ) = cos ( x ) {\displaystyle g(x)=\cos(x)} h ( x ) = 2 x {\displaystyle h(x)=2x} p ( x ) = x 2 {\displaystyle p(x)={\frac {x}{2}}}
( g ∘ p ) ( 60 ∘ ) = h ( p ( 60 ∘ ) = h ( 60 ∘ 2 ) = h ( 30 ∘ ) = 2 ⋅ 30 ∘ = 60 ∘ {\displaystyle (g\circ p)(60^{\circ })=h(p(60^{\circ })=h\left({\frac {60^{\circ }}{2}}\right)=h(30^{\circ })=2\cdot 30^{\circ }=60^{\circ }}
