Document Summary
Amounts to saying that the tangent line is the limiting position of the secant line approaches. Definition the tangent line to the curve the line through with slope. P at the point y f x . P a, f a is m lim x l a f x f a x a provided that this limit exists. Derivatives and rates of change: (see figure 3 where the case h 0. De nition: the tangent line to the curve y = f(x) a the point p(a, f(a)) is the line through that. , however, would be to the left of. In our rst example we con rm the guess we made in example 1 in section 2. 1. sion for the slope of the tangent line in de nition 1 becomes. ) and so the expres- is illustrated and is to the right of.
