Graph the curves and
.
Observe the graph:
\The curves on interval .
The curves are intersect at eight points.
\
Find the intersection points by equating the two curves.
\.
The general solutions on interval .

Find the other four intersection points.
\The curve is circle equation,
also gives the same circle as
.
Therefore, equate .
