Find an equation of the line that is tangent to fx x( )= 3 and parallel to the line 310xy− += The normal line has the opposite–reciprocal slope as the tangent line, so its equation is \begin{equation*} y \approx \frac{1}{3. This can also be explained in terms of calculus when the derivative at a point is undefined. So if the gradient of the tangent at the point (2, 8) of the curve y = x 3 is 12, the gradient of the normal is -1/12, since -1/12 × 12 = -1 . (a) 1, 1 .
