(Euclid) Given a secant line of a curve, as Q → P , the secant line approaches the tangent line at P, i.e., the tangent line is the limiting position. If P has coordinates (a, f(a)) and Q has coordinates (a + h, f(a+h)), then. and Example 1: Find the slope of the tangent line to the curve f(x) = 3 - 2x – 2x2 where x = 1.

(or a Secant and a Tangent) Vocabulary: and are called secant segments. and are called external segments of the secants. Theorem: When two secants intersect outside a circle, the product of the length of one secant segment and its external segment is equal to the product of the lengths of the other secant segment and its external segment. Proof:

In this limit the secant vector becomes parallel to the tangent vector, t (s), to the curve at the point s, so the numerator in measures the arc length along the curve. However, the arc length is s, so the ratio in becomes equal to plus or minus one depending upon the sign of the numerator. Taking the absolute value of the ratio we find |d. c
