The General Equation of the Tangent Line

The equation of the tangent line at P can be written y −f(a) = f(a) y = f(x) x y This is gives a general form for the equation of the tangent line to the curve y = f(x) at the point where x = a as y = f(a)+f′(a)(x −a) Clint Lee Math 112 Lecture 16: Linear Approximations and Differentials 2/7 The Tangent Line Approximation The Tangent Line ... ................
