Step 1:

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

The slope of the tangent line is equal to the derivative of the function at $\"\"$ .

Apply derivative on each side with respect to $\"\"$ .

$\"\"$

Step 2:

Slope at the point $\"\"$ , Substitute $\"\"$ in $\"\"$ .

$\"\"$

Point-slope form of line equation $\"\"$ .

Substitute point $\"\"$ and slope $\"\"$ in the above equation.

$\"\"$

Tangent line equation is $\"\"$ .

Solution:

Tangent line equation is $\"\"$ .
