Derivative is the slope of the secant line
WebThe precise definition of a tangent line relies on the notion of a secant line. The graph of function?(?) on the right and let 𝑃 1 be a point on the?(?). A secant line to?(?) through 𝑃 1 … WebWe can obtain the slope of the secant by choosing a value of x x near a a and drawing a line through the points (a,f (a)) ( a, f ( a)) and (x,f (x)) ( x, f ( x)), as shown in Figure 2. The slope of this line is given by an equation in the form of a difference quotient: msec = f (x)−f (a) x−a m sec = f ( x) − f ( a) x − a
