Example 1:Find the equation of the tangent line to the graph of at the point (−1,2). At the point (−1,2),f′(−1)=−½ and the equation of the line is Example 2:Find the equation of the normal line to the graph of ...
The normal line is a line that is perpendicular to the tangent line and passes through the point of tangency. Examples Example 1 Suppose f(x)=x3. Find the equation of the tangent line at the point where x=2. Step 1 Find the point of tangency. Since x=2, we evaluate f(2). ...
To find the equation of the normal line, take the derivative of the tangent line at the point on the curve. The slope of the normal line will be the opposite reciprocal of the derivative of the tangent line. We learned that the four steps of solving the equation of a normal line are ...
