Step 1:

\

The point is \"\".

\

Graph:

\

Draw the polar coordinate plane.

\

Plot the point \"\".

\

\"\"

\

Step 2:

\

The polar point \"\" generally represented as,

\

\"\"

\

\"\".

\

Put \"\" in \"\"

\

\"\"

\

Here \"\" is only in the interval \"\".

\

\"\" .

\

Put \"\" in \"\"

\

\"\"

\

\"\"

\

The two additional points of the \"\" are \"\" and \"\".

\

Solution:

\

Graphical representation of \"\":

\

\"\"

\

 

\

The two additional points  are \"\" and \"\".
