Step 1:

\

The polar coordinates: $\"\"$ .

\

$\"\"$ .

\

Polar coordinates $\"image\"$ .

\

$\"\"$

\

Substitute the values of $\"image\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Step 2:

\

Substitute the values of $\"image\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

$\"\"$

\

Solution:

\

Rectangular coordinates: $\"\"$ .
