Step 1:
\The equation is and the point is
.
Consider .
Differentiate on each side with respect to .
Slope of the tangent is derivetive of the function at the given point.
\.
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
.
Let slope of the normal as .
Therefore,
\Point slope form of line equation is .
Substitute and
in the above equation.
Normal line equation is .
Solution:
\Tangent line is .
Normal line equation is .
