Step 1:
\The equation is
and the point is
.
Consider
.
Differentiate on each side with respect to
.


Slope of the tangent line at
.

Slope of the tangent line is
.
Step 2:
\Point slope form of line equation is
.
Substitute
and
in the above equation.
Tangent line is
.
Normal line is perpendicular to tangent line then
\slope of tangent line*slope of normal line is equal to
.

Point slope form of line equation is
.
Substitute
and
in the above equation.

Normal line equation is
.
Step 3:
\Equation of circle with center
and radius
is
.
Differentiate on each side with respect to
.
