Line 40: Line 40:
x \ {\mapsto}\ \sin \left( \frac{{\pi \cdot x}}{2} \right) &\text{on $(0, 1)$} x \ {\mapsto}\ \sin ( \frac{\pi \cdot x}{2} )
Line 42: Line 42:

$$\ {\mapsto}\ 1 - {\left( x - 1 \right)}^{2} &\text{on $(1, 3)$}$$

$$x \ {\mapsto}\ -x &\text{on $(3, 5)$}$$

as follows:
on $(0, 1)$,
$$
\ {\mapsto}\ 1 - ( x - 1 )^2
$$
on $(1, 3)$,
$$x \ {\mapsto}\ -x $$
on $(3, 5)$, as follows:
