The equation of the curve is $\"\"$ and the point is $\"\"$ .

The slope of the tangent line is the derivative of the curve. \ \

$\"\"$ .

Differentiate with respect to $\"\"$ on each side.

$\"\"$

The slope of the tangent line at $\"\"$ is

$\"\"$

The equation of the tangent line at $\"\"$ :

Point - Slope form is $\"\"$ , where $\"\"$ is slope and $\"\"$ is the point on the line. \ \

Substitute $\"\"$ and $\"\"$ in above formula.

$\"\"$

The equation of the tangent line at $\"\"$ is $\"\"$ .
