Step 1 :
\The function is .
Consider the composite functions as and
.
Make a table :
\![]() | \
0 | \![]() | \
![]() | \
![]() | \
![]() | \
![]() | \
![]() | \
![]() | \
0 | \1 | \0.707 | \0 | \-1 | \-0.707 | \0 | \
![]() | \
1 | \0 | \-0.707 | \-1 | \0 | \0.707 | \1 | \
\
| \
1 | \1 | \0 | \-1 | \-1 | \0 | \1 | \
Point on the graph of f | \(0, 1) | \![]() | \

![]() | \
Graph the functions and
on the same coordinate system.
(1) Draw the coordinate plane.
\(2) plot the points.
\(3) connect the points with a smooth curve.
\The graph is :
