\

Step 1 :

\

The vector line equation is $\"\"$ .

\

Where $\"\"$ and $\"\"$ .

\

The parametric equations of a line :

\

$\"\"$ and $\"\"$ .

\

Step 2 :

\

The parametric equations are $\"\"$ and the point is $\"\"$ .

\

Substitute the point $\"\"$ in $\"\"$ .

\

$\"\"$

\

The point $\"\"$ is corresponds to $\"\"$ .

\

$\"\"$

\

Apply derivative on each side with respect to t.

\

$\"\"$

\

Substitute $\"\"$ in above equation.

\

$\"\"$

\

Write the vector notation in component form.

\

$\"\"$

\

The equation of a tangent line passing through the point $\"\"$ is

\

$\"\"$

\

The parametric equations are $\"\"$ and $\"\"$ .

\

Solution :

\

The parametric equations are $\"\"$ and $\"\"$ .
