Chapter 10.6, Problem 91AYU

Descartes’ Method of Equal Roots Descartes' method for finding tangents depends on the idea that, for many graphs, the tangent line at a given point is the unique line that intersects the graph at that point only. We apply his method to find an equation of the tangent line to the parabola

y   =   x 2 at the point ( 2 ,   4 ) . See the figure.

Chapter 10.6, Problem 91AYU, Descartes’ Method of Equal Roots Descartes' method for finding tangents depends on the idea that,

First, we know that the equation of the tangent line must be in the form y   =   m x   +   b . Using the fact that the point ( 2 ,   4 ) is on the line, we can solve for b in terms of m and get the equation y   =   m x   +   ( 4   −   2 m ) . Now we want ( 2 ,   4 ) to be the unique solution to the system

{ y   =   x 2 y   =   m x   +   4   −   2 m

From this system, we get x 2   −   m x   +   ( 2 m   −   4 )   =   0 . By using the quadratic formula, we get

x   =   m   ±   m 2   −   4 ( 2 m   −   4 ) 2

To obtain a unique solution for x , the two roots must be equal; in other words, the discriminant m 2   −   4 ( 2 m   −   4 ) must be 0. Complete the work to get m , and write an equation of the tangent line.
